Alpine Tips
Plan a multi-day backpack trip with GaiaGPS.com
Modern navigation tools can be a tremendous help for wilderness trip planning. Check out this in-depth video on planning a multi day backpack trip using GaiaGPS.com, which covers many of the more advanced features. (Not just for backpackers, has applications for just about any wilderness trip.)
This video was made by Travis Prescott, who is an expert digital navigation instructor for the Seattle Mountaineers. Check out Travis’ website, TheAlpineGeek.com.
Backpackers: watch this excellent video and learn how to use modern navigation tools like GaiaGPS.com to plan a multi-day trip. (The example is for a backpack trip, but it certainly has applications for other types of wilderness travel.) The video is a bit longer than most, about 30 minutes, but it gets into some of the more advanced features of GaiaSGPS.com that make it such an effective planning tool.
Here are a few of the many trip planning tips covered in the video:
Using the “snap to trail” feature to make a track that exactly follows your trail
Using the “elevation profile” feature to figure out steepness and length of each trail segment
Stacking different map layers on top of each other by changing the opacity of a layer
Using folders to keep your map data organized
Creating waypoints with a name, color and symbol
Finding possible campsites and water sources
Using the Gaia “Public Tracks” map layer to see possible cross country scramble routes
A clever use of the “roadless areas” map layer to show where bail out possibilities might exist
And that's just what I remember. There’s more, good stuff, check it out!
Below is a screen grab, showing each segment of a multi-day trip, and campsite location.

Gear Breaking, Italian Style
You don't want to break your equipment, but it sure is fun watching other people do it! Check out this great video from the Italian Alpine Club, which shows testing and breaking all different kinds of climbing gear. (The original was in Italian; I paid to have subtitles added.)
Let's get one thing straight. The CAI has a terrific logo. =^)
Click below to watch the video.
As climbers, we never want our gear to break. But it sure can be fun watching people do it in the lab!
The Italian Alpine Club (Club Alpino Italiano, or CAI) founded in 1863, is the second oldest alpine club in the world. They have been doing gear tests like this for more than 50 years. They made a terrific video showing all manner of testing and destruction - ropes (both sudden drop test and slow motion steady pull, with and without knots), slings, carabiners and harnesses. Also, various tests of the flat overhand bend, with different combinations of rope material and diameter. Girth hitch? Yep, we got that too.
Lots of these gear testing videos are in the original language, often Italian or German. I paid to have subtitles added to this video so this important information could be brought to a wider audience. (That's why it's on my YouTube channel, but all content is from the CAI.)
Note, the units in this video are the kind of unusual “kgf”, or “kilogram force”. This is different than the more commonly used kilonewton (kN), which has a climber you are hopefully familiar with.
Fortunately, the math conversion is easy: simply move the decimal two places to the left for an approximate conversion to kilonewtons. For example, if something in the video broke 1268 kgf, move the decimal place to places to the left and you get around 12.6 kN. (technically it's about 12.4, but hey I'm not an engineer and that's good enough for me.)
Yep, they tested Dyneema girth hitches.
Plus the flat overhand bend, in lots of different combinations of material and diameter.
What are climbing forces in the real world?
Most climbing gear is tested in the harsh environment of a drop tower, but that doesn't tell the whole story when it comes to real world forces. Check out this article and video series from Petzl, where they try to answer what are realistic forces throughout the system when tested on real live people.
When measuring forces on climbing gear, most tests are done without human bodies, using very harsh falls onto a fixed point. Well, fortunately the clever gear testers at Petzl got some real-world results more relevant for actual climbers.

First, a video from Petzl.
They put force measuring devices on the belayer, the climber and the top piece of gear, had them take some increasingly severe falls, measured everything, and took video.
The belay device was a Grigri 2.
They summed everything up with clear diagrams, short videos showing some big falls, and some conclusions - yet another reminder why the Petzl website is great!
Disclaimer: there are many variables involved in testing forces like this. This is not a comprehensive study with definitive results, but more of a way to get people thinking about general technique and assumptions.
Click the button below to see this great article and videos for yourself.
Here are some personal takeaways. What are yours?
Even in a relatively low factor fall, due to rope stretch and belayer displacement, the falling climber can go a VERY long way.
The relatively low numbers help explain why a knotted Dyneema sling rated to 22 kN may break in a harsh drop tower test, but is extremely unlikely to break in the real world.
The upward movement of the belayer when catching a fall can do a lot to lower the forces on the climber and the gear.
Using an assisted braking belay device such as a Petzl Grigri is an excellent choice if you think you're going to be catching some major whippers. (But you already knew that, right? =^)
Even in a high force, factor 1 fall, there’s relatively little force on the belay anchor. Only a tiny bit more than a factor 0.3. Low forces on the anchor, that's good!
You can’t really do you “live body” testing like this with much more than a factor 1 fall, because somebody's gonna get hurt.
I know, you're wondering what about that dreaded, mythical factor 2 fall, the one that pretty much never happens in the real world, but still the one everybody's worried about? To protect against that, you can do a few things. The best one is for the leader to place so in gear as soon as possible after leaving the anchor. If that can’t be done, you can consider a fixed point belay. This doesn’t change the fall factor, but it gives a higher likelihood of a successful catch in the event it happens, without slamming the belayer into the wall. Another option, for more extreme situations, if the terrain allows it, is for the belayer to lower themselves down below the actual anchor, to put more rope in between them and the leader, and then have the leader clip the anchor is the first piece.

Second, a video from How Not to Highline.
Ryan Jenks, the creative force behind the popular YouTube channel How Not to Highline, measured a bunch of gym falls in a similar way. Below are some of his numbers. While perhaps not a rigorous scientific study because some variables changed from test to test, it does provide interesting numbers.
Fall factors were not measured, so it's a little hard to compare directly to the Petzl study. Note that the measured force never exceeded 5 kN in any part of the system . The only time it came close were static fall and a Z drag fall, where it got close to 5 kN on the top piece of gear.
There are many, many variables to consider when trying to determine these numbers, but these two studies can give you a rough idea of real world forces on the belayer, on the climber, and on the top piece of gear.

What angle is best for ice screws?
Most ice climbers know that a screw angled down in good quality ice is stronger than one angled up. Black Diamond tested this; here are the real numbers. Plus, in real life conditions, where you can't always assess the quality of the ice, there's a good argument for using an angle of 0° all the time.
Most ice climbers know that a screw placed with threads pointing UP in good quality ice is stronger than one with threads pointing DOWN.
How about some real data, please?
Chris Harmston and the gear testing experts at Black Diamond have some answers.
image: https://www.needlesports.com/Information/Need-Advice/Ice-Screw-Placement
The difference in strength is dramatic - about 9(ish) kN for the screws tilted up, vs. about 22)ish) kN for the screws angled down. Most ice climbers know that a screw pointed down in good quality ice is stronger, but here are some real data to back that up.
Why is this? An comment on my Instagram from @willmurphy6612, explains:
”It has to do with how the load is displaced in the ice. When the threads are perpendicular or pointing UP, the load is transferred axially along the length of screw. This takes advantage of the compressive strength of ice.
When the threads are pointing DOWN, part of the screw is loaded radially which exploits the shear strength of ice, which is not very good. Combine that with the fact that the cracks initiated by the screw are propagating to the surface when angled DOWN the load strength of the system is severely compromised.”
Thank you Will, nicely said!
Note that there are many more variables and play here: the length of the screw, the type/brand of screw, is there a chance the screw might melt out, and above all the quality of the ice. Check out this link to learn more about these factors, and how the test was conducted.
From this BD article on ice screw placement strength:
“There has been a lot of discussion over the years surrounding placement angles. It is generally understood that the strongest placements are between 10 and 15 degrees in the positive direction (teeth upward). The ice surrounding the screw is the weak link in the system, so the goal is to place the screw in a way that reduces the stress on the ice.
An upward-placed screw reduces the compressive stresses in the surrounding ice and better aligns the threads on the screw body with the fall direction—both of which increase holding power. As the screw moves towards negative placement angles (teeth downward) the holding power of the threads decreases and the stresses in the ice increase due to the levering action of the screw.”
Notice the strength at the purple oval / zero degrees - all above 13 kN, which is more than you would ever encounter in any climbing fall. Super good enough!
In their excellent book “The Mountain Guide Manual”, authors Mark Chavin and Rob Coppolillo write that they feel it's best to place screws at zero degrees / perpendicular.
Their reasoning: While in perfect ice tilting the screw downward can result in higher strength, in less than perfect ice, screws at 0° hold the best. Because it's often hard to judge the quality of ice for the full depth of the screw, they feel that defaulting to perpendicular is the best approach.
Along with these test data that show 0 degrees is plenty strong enough, that seems like a good choice.
Debunking anchor/climbing myths, Part 1
There are some well-meaning but perhaps misinformed ideas about acceptable anchor building practices. Let's have a close look at an anchor, made by an IFMGA Guide, that might cause you to question some of your assumptions.
The anchor example below is from Dale Remsberg, an IFMGA Certified Guide and Technical Director of the American Mountain Guides Association (AMGA). Dale posts a lot of great climbing and anchor photos that make you really think about rigging! Follow Dale on Instagram and Facebook to keep your anchor brain engaged. (Photo used with Dale’s permission.)
Here's a good rule of thumb when talking about different climbing techniques - Use the words “never” and “always” with restraint.
If a technique is unfamiliar, it doesn’t necessarily mean that it's incorrect.
Conversely, a technique you’re familiar with (and may have been using for a long time) isn’t necessarily the only valid approach - and may actually not be the best practice.
Let's have a look at some long-running misunderstandings, myths, and hearsay, mostly related to anchor building. Maybe we can put some of these well meaning but perhaps misinformed ideas to rest.
There’s a lot going on with Dale’s anchor. Let’s dive in.
image: Dale Remsberg, https://www.instagram.com/p/B1ll_DZDtEi/
1 - “You should NEVER clip carabiners or other gear into the rings/quicklinks you rappel from. Doing this can cause a nick / burr / damage on the rappel hardware, which could then damage someone’s rope.”
Almost all recreational climbers use aluminum carabiners. Almost all anchor hardware is made of steel. Aluminum is a softer metal than steel, so your aluminum carabiner is never going to cause any damage to steel anchor hardware. It's like cleaning your icy car windshield with a plastic scraper; the plastic will never scratch the glass.
However, the opposite can be true - a sharp edged steel bolt hanger can definitely put some nicks in an aluminum carabiner. That's one of the reasons why sport climbing quickdraws are designed to have one carabiner that always clips in the bolt, and one carabiner to clip the rope. (If you’re taking a lot of falls onto a quick draw, check the top carabiner and retire it if it's getting chewed up.)
Usually, it’s also okay to clip the bolt hangers. But, this can depend on the size and configuration of the hardware. Sometimes, clipping the bolt hanger can result in the carabiner possibly being loaded over an edge of a chain link or other non-optimal manner. If you clip the bottom ring, the carabiner is almost always going to hang free and in the correct orientation.
Photo: Blue and gold carabiners clipped directly to the rappel rings.

2 - “You should NEVER clip one carabiner to another.” (aka, metal on metal is bad)
In certain situations, like chaining together several non-locking carabiners, this is correct. However, if they’re locking carabiners, and you’re right there to monitor them so they don't get loaded in a weird way, clipping one carabiner to another is fine. Big wall climbers do this all the time; a large HMS “pearabiner” gets clipped to each belay bolt, and then many subsequent carabiners may get added onto that first one.
Photo: One locking carabiner as the master point, and two more locking carabiners clipped into that.
image: Dale Remsberg, https://www.instagram.com/p/B1ll_DZDtEi/
3 - “You should ALWAYS use locking carabiners everywhere when building anchors.”
The carabiners clipped to the individual pieces of protection in an anchor do not need to be lockers. It’s nice to have your master point carabiner be a locker, but if you don't have one, two regular carabiners clipped opposite and opposed is okay also.
Key point: use a locking carabiner (or at least two opposite and opposed standard carabiners) at any sort of critical link, if the failure of that link would be YGD (Yer Gonna Die).
If you’re in an instructional setting, and building a top rope anchor that’s going to have multiple climbers, you’re probably not going to be there to regularly inspect it. In this case, many people will choose to use locking carabiners everywhere, and that's fine.
Hey, and even on a multi pitch anchor like this, if it gives you greater peace of mind, and you have gear to do so (5 lockers) it's completely fine if you want to put lockers on every component of the anchor. But also know that it's fine if you want to rig it as shown.
Photo: The blue and gold carabiners clipped into the rappel rings are not locking. This is okay, because it's not a critical link.

4 - “A statically equalized, cordelette style anchor should ALWAYS have an overhand or figure 8 knot to make the master point.”
This has been the standard approach for a long time. But depending on your circumstances, there might be better options. You can use a clove hitch or a girth hitch at the master point also. Why do this?
Uses less sling material, so it works when you might only have a single length runner
Easier to untie after it's been loaded
Easier to untie if hands are sore and/or cold, or if you’re wearing gloves
Keeps the master point carabiner properly oriented; it can never spin and become cross loaded
Photo: girth hitch at the master point.
image: Dale Remsberg, https://www.instagram.com/p/B1ll_DZDtEi/
5 - “There's something wrong with an anchor if it doesn’t have a shelf.”
A shelf on a “cordelette style” anchor is a convenience, not a requirement. Strength of the placements and load distribution can be considered the most important components of an anchor. A shelf is optional. There are lots of acceptable anchors, like this one, that don’t have a shelf.
Photo: A girth hitch or clove hitch at the master point doesn’t provide a ready-made shelf. That’s okay.
image: Dale Remsberg, https://www.instagram.com/p/B1ll_DZDtEi/
6 - “You should ALWAYS use a tether / leash / PAS / Purcell prusik as your primary attachment to the anchor.”
Well, fortunately this concept is not nearly as widespread as a few years ago, which is a fine thing. Whenever possible, you should use the climbing rope to attach yourself to the anchor. The rope is the strongest and most dynamic / stretchy part of your climbing gear, so use it! Only use a tether / leash / PAS for those times when you can’t use the rope, such as when you’re rappelling, when you’re part of a larger team and using the rope is maybe not practical, or when you're big wall climbing and the rope is otherwise occupied.
Photo: The clove hitch on the bottom right carabiner directly connects the climber to the anchor master point with the rope.

7 - “All parts of an anchor ALWAYS need to be redundant.”
Redundancy in anchors can be thought of as: if one single component fails, entire anchor does not fail. This is generally a good policy, but it doesn't always apply to every component. In the photo, several parts of the anchor are not redundant - each of the 3 gold locking carabiners, and the rope.
At some point, you need to have some faith in your gear. One locking carabiner in good condition, with the gate securely closed? Like the three lockers in the bottom half of the anchor? Good to go.
A locking carabiner in good condition, made by a reputable manufacturer, tested to the highest requirements, and properly locked and loaded along the spine has never failed in the history of climbing, as far as I've heard. So, it's something you can rely upon as a single non-redundant connection.
Here's a complete article on the issue of redundancy in anchors, if you want to take a deeper dive.
Debunking anchor/climbing myths, Part 2
Just because you learned to do it a certain way doesn't necessarily mean that's the right approach or current best practice. Let's have a look at some common climbing techniques and explore some alternatives.
Here's something to consider when talking about climbing techniques - Consider using the words “never” and “always” with restraint.
Let's have a look at some long-running misunderstandings, myths, and hearsay. Maybe we can put some of these well meaning but perhaps misinformed ideas to rest.
“I saw the DMM video where they broke Dyneema knotted runners in drop tests. So, you should NEVER tie a knot in Dyneema; it weakens the material to a dangerous level.”
Wowzer, this one can really get people riled up on the interwebs! Opinions range from “Yer Gonna Die (YGD)”, to “Generally not best practice, but it’s probably okay”, to “No worries, not a factor in real world climbing.” Might the truth be somewhere in the middle?
Here’s my short answer: Yes, it does weaken the webbing, depending on the knot, let's say 50%. But, a sewn Dyneema runner is rated to about 22 kN, so even if you reduce the strength of that half, you still have a strength of around 11 kN. The maximum force possible in any real world climbing scenario is about 9kN, and that is in the extremely rare scenario of a very harsh factor 2 fall. Even when catching a factor 1 fall, the force on the anchor is only about 2 kN.
The technical documentation on Dyneema slings from Black Diamond and Petzl does not expressly forbid knots in Dyneema. Black Diamond mentions it as a “caution”. But they also mention as a “caution” getting water, ice, or mud on your slings, which we know is hardly the end of the world. (Plus, they also have the same caution warning on a nylon sling, so it's not just a Dyneema thing.)
Thus, the diminished strength that comes from the knot doesn't really matter in real world climbing scenarios. Yes, it can break in a drop test. No, it doesn’t break in real life. Think of it this way: tens of thousands of climbers have tied knots in Dyneema for decades, but have you ever heard of a knotted sling breaking in real life? No.
Here's another way to think about: 11 kN is as strong or stronger than any gear placement, stronger than the force a dynamic rope will create, and more than your body can handle.
Many IFMGA certified guides use and teach this technique regularly.
Having said that, if you don't like it, then don't do it. But, no need to criticize others if they choose to tie knots in Dyneema.
Below: Quad anchor tied with overhand knots in Dyneema webbing (photo and anchor by Dale Remsberg, an IFMGA Certified Guide and Technical Director of the American Mountain Guides Association (AMGA).

“You should NEVER connect your tether/PAS to your belay loop. Todd Skinner did that, his belay loop broke, and he died. So, you shouldn't do it either.”
or maybe:
“You should ALWAYS run soft goods, like rope and slings, through the tie in points, and clip hard goods, like carabiners, to the belay loop.”
When ascending a route, it's usually best practice to use the rope and clove hitch yourself to the anchor. But when it's time to rappel, you're probably going to want a tether. Whether you use a designated tether like a PAS or a Petzl Connect, or make one DIY with a double length sling, you need to choose how to connect it to your harness.
There are some cases when attaching your tether directly to your belay loop is not only acceptable, but the recommended practice. There are some other situations where it's probably not such a great idea.
What activity are you doing?
What does the manufacturer say?
What’s your tether made of?
What kind of knot or hitch connects the tether to your harness?
These are all nuances in technique that need to be considered, rather than a binary “always” or “never.”
Here are some general guidelines:
Regarding Todd Skinner's tragic death, he apparently was rappelling fast on static ropes. The bottom of the rope was tied to the lower anchor (the “J loop”). Todd rapped into the bottom of the loop at speed, and when he hit the bottom of the loop, this large static force caused his harness to fail. It did not happen under a standard body weight rappel. (Source: Andy Kirkpatrick, “Higher Education”, page 182., and private Instagram message from Will Gadd.) Todd's harness was extremely old and worn out. Check your harness regularly and retire it without hesitation if it shows significant wear for any reason.
If you do connect a tether to your belay loop, don’t leave it permanently connected. Doing this can prevent the loop from rotating and may concentrate wear in a single spot. Remove the tether when you're done for the day, or after your rappel.
If you're girth hitching a designated PAS type tether, the usual manufacturer recommendation is to use both tie in points. (Even then it's a bit of a “soft” recommendation.)
If you're girth hitching a “DIY” tether with a skinny Dyneema sling, it’s probably best to use both tie in points. (Plus some people think it’s best not to use a static Dyneema sling as a tether at all.)
If you're girth hitching a tether (or adjustable daisy for aid climbing) with a wider nylon sling, either the tie in points or the belay loop should be fine.
If you're using a rope style lanyard such as the Petzl Connect Adjust, follow Petzl’s recommendation and girth hitch it to your belay loop.
If you’re doing via ferrata, the standard practice is to girth hitch the lanyards to your belay loop.
Many world class climbers and IFMGA Certified Guides prefer to use the belay loop.
And . . . if you're not using a girth hitch and using a double loop bowline tether, it's okay to tie it through your belay loop with any kind of material.
Again, to learn more about this, check out this detailed article.
“You should ALWAYS rappel off of sport climbing anchors. If you lower off, it wears out the anchor hardware.”
Many older climbers were brought up with this ethic. However, the modern approach to getting the last climber down from a sport anchor is to lower through the anchor hardware. Why?
Most modern hardware is designed to be easily replaced
Lowering can reduce communication errors between the climber and the belayer
The climber never goes off belay
There’s less chance of dropping the rope
You don't need any extra gear like a leash or a rappel device
Most of all, it’s the recommended practice from the American Alpine Club. You can see an entire article about it here.
Note, this only applies to the LAST climber. Generally, the first climber should build an anchor with their own gear, and lower of that. This is especially true if you are a top roping with a larger group or doing multiple laps.
And yes, some climbing areas have a local ethic of always rappelling for the last person. If you’re climbing somewhere new, ask about preferred technique. It's up to you to choose between getting a stinkeye from the locals and using modern best practices.
General procedure of what's going on below: 1) Climber pulls a bight of rope and threads it through the anchor chains. 2) Climb a ties a figure 8 loop and clips it to her belay loop with a locker. 3,4) Climber then unties her tie in knot and pulls the tail through the chains. 5,6) After clear communication with the belayer, climber calls for a lower. Note, she stays on belay the entire time. Diagram, Petzl.com

“You should NEVER load a carabiner in 3 or more directions; doing so weakens it dangerously.”
Hopefully you learn early on in your climbing that whenever possible you should load a carabiner along the spine, and always avoid cross loading across the gate, which can reduce the strength of the carabiner by about 2/3. Good advice, always do this when you can.
But, there are some other situations where a carabiner can be loaded in three or even four directions, such as in the photo below. What's the story on that? Is it dangerous?
Turns out, for recreational climbers, this is probably fine. Black Diamond did some break testing on this, and even under extreme loading in four directions (known as quad-axial loading) , the carabiner only lost a maximum of about 25% strength, down to around 15 kN.
Setting up an anchor as shown in the photo below to belay your second, where the maximum force is probably going to be at most 3 kN, is acceptable. Again, you don't have to do it yourself, but if you see someone else rigging it like this, know that it's well within the breaking limit of the equipment. (And, loading in three directions, known as tri-axial loading, showed hardly any reduction in strength in the carabiner.)
We cover this extensively and share the Black Diamond results in this article.

“When you tie into your harness, you should ALWAYS tie a ‘safety knot’ to backup your rewoven figure 8 knot.”
A “backup” knot is unnecessary. This myth is further propagated by many rock gyms (and maybe their overzealous lawyers?) who require this practice. A proper rewoven figure 8 has a good long tail of at least 6 inches, and has been properly “dressed and stressed”, so all the slack is pulled out of it. Once you do these two things, there's no need for a so-called safety knot, backup knot, or anything like that.
Rewoven figure 8, good to go, no backup knot. (Okay nitpickers, the tail could be a few inches shorter . . .)
How to lead a roof on aid, by Petzl
Aid climbing through a roof can be insanely awkward and strenuous . . . or, pretty straightforward if you have the proper gear and technique. Check out these great diagrams from Petzl on how to do it, and learn some ways to practice before you get on the real stone.
Aid leading through a roof can be incredibly strenuous and awkward . . . or, if you have an adjustable tether, it can be pretty straightforward.
The always amazing Petzl website has a nice sequence of diagrams of how to do this. They show it using their nifty Petzl “Evolv Adjust” adjustable tether designed for aid climbing, but any sort of adjustable tether, such as the popular Yates, will work.
In fact, you may find the Yates tether actually works a little better, because it's easy to release under tension, while the Petzl one is not, at least for me.
If you're a beginner aid climber and your route has any sort of a roof on it (such as the famous “Kor Roof” pitch on the South Face of Washington Column in Yosemite), studying the sequence below will be extremely helpful, hint hint!
Practice! If you're in Yosemite, before you head up the wall take a training lap or three on the LeConte Boulder, which has a nice practice bolt ladder on it. If you don't have any real rock, get resourceful: hang some slings from the underside of an outdoor staircase/fire escape, a stout tree limb, or something similar. Please, do yourself (and any teams that might be stuck behind you) a big favor, and get this critical skill dialed before you try it on a real route.
The link to the Petzl website showing these drawings is here. But, if this page disappears, I screen grabbed the diagrams and put them below. (Dear Petzl graphic design department: You’re amazing! If you want to pick up a little freelance work on the weekends, please give me a call.)
All images below are by Petzl.com
Notes: Lanyard to A is cinched in tight. Feet can give some opposing tension to make the clip to B. The first thing clipped to B is a quick draw. Your lanyard and aider get clipped to the top carabiner of the quick draw.
image: https://www.petzl.com/INT/en/Sport/Aid-climbing-progression
Using your nifty adjustable tether, put some tension on B. (This is about the time when you'll want to kiss the person who invented adjustable tethers . . .)
image: https://www.petzl.com/INT/en/Sport/Aid-climbing-progression
This can be the tricky part. You need to release your weight from the adjustable tether off A, and slowly lower yourself out to hang beneath B. Having an adjustable tether that can release in a controlled way while under tension makes this process a LOT easier! Note in the diagram below, the climber is pulling toward A with their left hand, to create a little slack so they can do a little lower out with the tether.
image: https://www.petzl.com/INT/en/Sport/Aid-climbing-progression
Walk up the ladder hanging from B, and use your adjustable lanyard to hoist yourself up close to B. Then clip the rope to the bottom of the quickdraw. Repeat this sequence as needed to clear the roof.

What’s “nose hooking” a carabiner?
A “nose hooked” carabiner can fail at an extremely low load. Fortunately it's easy to notice and fix, so be aware of this potentially dangerous situation.
Nose hooking a carabiner is about what it sounds like: getting the “nose” of the carabiner stuck on a bolt hanger, stopper wire or webbing without the gate completely closing. Carabiners are extremely weak in this orientation and can break in a very modest fall or even bounce testing.
If you ever see a carabiner in this configuration, stop and fix it immediately.
Black Diamond did some testing on this, and carabiners failed as low as 2 kN, YIKES! (Side note, if you're a gear nerd and like to read about gear testing, the Black Diamond QC Lab Archives has some interesting reading.)
Nose hooked carabiner on a bolt hanger.
Nose hooked carabiner on a sling.
Fortunately, there’s a solution: use a keylock / notchless carabiner. The smooth, notchless nose makes it almost impossible to nose hook.
Just about every modern solid gate carabiner is made like this, but many wiregate carabiners are not. A few wiregate carabiners are notchless: the Camp Dyon, Wild Country Helium, DMM Chimera, and Petzl Ange (below) to name a few.
Petzl Ange notchless wiregate carabiner
And, related to this, is the reason why the top carabiner in a quick draw must be allowed some rotation in the dogbone sling and not used with any sort of a rubber device like a Petzl String. The rubber device can prevent the top carabiner from rotating and result in nose hooking or (below), levering the carabiner at a bad angle .

Here's a way to repurpose some gear at your big wall bivy so you’ll never spill that precious can of . . . prune juice.
This tip come from big wall ace Pete Zabrok and his excellent new book “Hooking Up - The Ultimate Big Wall and Aid Climbing Manual”. Highly recommended for aspiring aid climbers!
One of the more vexing questions for big wall climbers is, “Where da heck do I put my beverage?! The last thing you want at your bivy is spilling that precious can of . . . prune juice, but there is a serious lack of flat spots to put it. (An extra chalk bag, of course without chalk, also works well with this.)
Fortunately, resourceful big wallers came up with a crafty solution.
Use CalTopo layers in Google Earth
If you have a Caltopo subscription, you can view all of those cool map layers as overlays in the 3D splendor of Google Earth. Warning - for map geeks only . . .
If you're new to using CalTopo mapping software, watch this tutorial to get started.
Disclaimer: This article is pretty much for map geeks only. Having said that, it’s pretty darn cool and you might well find some uses for it that I can’t imagine. I've been a CalTopo nerd for many years, and I didn’t know about this feature until recently, so I thought I’d share it.
Have a quick look through the photos below, and if it looks interesting, give it a whirl.
Here's how it works: If you have a paid subscription to CalTopo (and you should, it’s well worth it) one benefit is access to what are called “Super Overlays.”
What the heck is a Super Overlay? It lets you use pretty much all of the CalTopo map layers in the 3-D splendor of Google Earth!
(The helpful tips on this CalTopo blog/help page cover it pretty well.)
Login to your CalTopo account. Click your email address in the upper left corner of the CalTopo screen, then click the “Account” tab. You should see a screen that looks something like the screen grab below.
See that arrow and the red box at the bottom after the “KML”? That’s the “super overlay” KML file you want.
Right click that link to download the super overlay KML file to your hard drive.
Then, open it in Google Earth. (Tech note: “KML” is a type of a geographic data file that plays nicely with Google Earth.)
I blocked out part of the link because the CalTopo team does not want people to share it. You need to pay for a subscription and get it yourself.
For this example, we’re looking at the Mt. Whitney area in the California Sierra.
Once you open the super overlay KML file in Google Earth, you should see a menu on the left that looks something like the red box in the screen grab below.
If you check any of these boxes, that map information from CalTopo will overlay onto Google Earth.
I suggest checking ONLY one layer at a time, and zooming into a fairly small area so it redraws fairly quickly, depending on your computer speed and web connection speed.
Some layers are more helpful and interesting than others. Try a few and see what you think. Some examples are below. (Note, these layers look MUCH more impressive on a full width desktop computer screen than the screen grabs below.)
Here’s the 20 meter contour layer overlaid onto Google Earth.
Here’s the custom CalTopo layer “MapBuilder Topo” layer overlaid onto Google Earth, with trails, shaded relief, streams, wilderness boundary, and more.
Another interesting overlay is slope angle shading. These are indicated by the “Fixed” and the “Gradient” boxes. Here's the Emmons glacier route on Mt. Rainier. You can see how the route pretty much takes the path of least resistance/lowest angle slopes.
Hopefully you get the idea. Zoom in to an area you’re familiar with, load up a few CalTopo layers in Google Earth, and have fun playing in the sandbox!
Pocket Fresnel lens for the small print
Carrying a credit card sized Fresnel magnifying lens can really help with reading the small print on a map or your phone. Good news, they weigh pretty much nothing, have 3X magnifying power, and cost about $1 each.
So, the way I heard the story . . . Several older and experienced hikers were hiking in the Columbia River Gorge. As light was fading, they needed to make a route choice at a trail junction. They pulled out their map . . . and couldn’t read it because no one had reading glasses! They didn’t know where to go, and decided to stay put for the night. (That was probably the best choice, and luckily they had the gear to do so in reasonable comfort.) The next morning, when there was enough light to read their map, they walked out unassisted.
For more “well seasoned” climbers, reading the small print on a map or phone screen can be tricky. But who wants to bring reading glasses on a hike or climb?
A lightweight, inexpensive, and functional solution is a pocket Fresnel (pronounced fruh-nel) magnifying lens.
image: https://www.amazon.com/Outus-Plastic-Reading-Magnifier-Firestarter/dp/B06W5FCS4Q/
These little puppies are simply thin, flexible, plastic magnifying glasses. About the size of a credit card, they are dirt cheap, magnify to about 3x power, and really help to read that 8 point font. (The image clarity is not as good as what you’d get with a lens actually made of glass, but it’s probably good enough to read your map and make the correct trail choice.)
If you want to show off your bushcraft skills, they can apparently be used in a pinch to even start a fire, provided you have steady hands, perfect tinder, and bright sunshine. (Disclaimer, I have never done this, your mileage may vary, and YouTube is your friend.)
You can get a multi-pack of pocket magnifier lenses online for something like $1 each. So, buy a bunch, keep them scattered around your gear bags, and give ‘em away to your friends. Search Google for “pocket Fresnel lens”.
Science geek note: the Fresnel lens was invented by a French physicist in the 1800s, and was originally used in lighthouses to concentrate the light beam. Several excellent examples can be seen at historic lighthouses, including several in Oregon. When seen full size in a lighthouse, they are quite amazing!

Decluster your anchor: Put lap coils on a sling
At a hanging belay or small stance, keeping your rope tidy and giving a smooth belay to the leader is a lot easier if you move the coiled rope away from your tie in connection and attach it to some part of the anchor.
This tip is from AMGA Certified Rock Guide Cody Bradford. While sadly Cody is no longer with us, his Instagram continues to stay up and is a great source of tips like this, check it out.
On a multi pitch climb, rope management is a key skill to staying cluster free and moving efficiently. The basic question is, ledge, or no ledge?
If you have any sort of a ledge, you can often (neatly) pile the rope at your feet.
If you're at a small stance or full hanging belay, the typical approach is to make lap coils over your tie in connection.
However, these lap coils can be cumbersome, especially when belaying a leader.
Below is the standard approach of the rope draped over your tie in connection. Do you think this might be awkward when you try to belay your leader from your belay loop? (Answer, yes.)
image: Cody Bradford, https://www.instagram.com/p/BsZCqrpBXpu/
Solution: hang the coils from a sling on the anchor. The rope stays tidy AND out of your way. Much easier to belay your leader on the next pitch.

Here's a short video by Cody Bradford that demonstrates this simple and effective technique. (He's doing it on ice, but it works fine for rock climbing as well.)
Bounce test to learn gear placement
Learning how to place rock gear, and want a little assurance that your pro might be able to take some real force? You can learn a lot without getting more than a foot or two off the ground by bounce testing at your local crag.
Starting out learning to place trad gear and build anchors? It looks like a decent placement, but is it really going to hold? A great way to build confidence in your gear placements (as well as get lots of practice using your nut tool) is take a page from big wall climbing: bounce test your gear.
While a bounce test is probably going to put between 2 and 3 kN on your piece, quite a bit less than the maximum force of about 6 to 7 kN it might see in a big actual fall, it can definitely boost your confidence that you’re placing your gear correctly.
The image below is a screen grab from a video from our friends at HowNot2.com, showing the actual force generated during a static sling bounce test.
image: HowNot2.com, https://www.youtube.com/watch?v=gq3_DfyHg1A&t=781s
You may hear advice of “go aid climbing” to learn how to place gear. Not a bad idea, but it does require lots of extra stuff like a rope, a patient belay partner, and aiders, fifi hook, daisychains, and probably ascenders. You actually don't need any of that; you can bounce test and get the same learning pretty much standing on the ground.
What you need: base of a cliff area with lots of various sized cracks to place gear, a decent trad rack (can maybe borrow from a good friend), a cleaning tool. Optional but suggested: a hammer and eye protection/safety glasses.
How to do it: At the crag, make a placement that you can reach from the ground, and clip a runner or two to the gear. Extend runners as needed so when you step in it, it’s about knee level. (You want to keep your feet close to the ground when you do this because if the piece pops out, that means you won't take much of a fall.)
Give it a decent tug.
Did it move? Does the rock on either side look solid? Good.
Now, carefully step into the runner, and give it a little bodyweight. (If the placement is near or above your head, you might want to cover the gear with your hand. If the gear pops, it’s going to zing out somewhere in the neighborhood of your eye - remember those suggested safety glasses?) Did the gear move it all? If not, sweet, probably a good placement.
Now, start jumping on the sling with increasing enthusiasm. Did the gear shift a little bit and then hold? Might be OK, but probably could be improved. Did it sprout wings, fly out of the rock and almost hit you in the eye when you jumped on it? Definitely needs more work.
And, like I said, be sure and bring a cleaning tool and perhaps a hammer, or at least a baseball sized rock or big hex, so you can (gently) beat on those welded stoppers to be sure you take everything home. (You might not want to bounce test a Tricam, which are notorious for being hard to clean after they’ve been weighted.)
It’s one thing to put in a piece of gear, look at it, and hope it’s well placed. It’s quite another to jump on it with enthusiasm and know with more certainty. If you have a more knowledgeable friend to work with on this, they can critique your placements.
Here's a nice short video that shows the basic technique. (Note that here it's demonstrated using standard big wall equipment such as aid ladders and daisy chains, but pretty much the same procedure can be done very close to the ground with a few slings.)
And finally, here's a video from our friends at HowNot2.com showing the actual force is generated from bounce testing. (it's a long video, start at 13:00 to see the testing part.)
Snow picket - vertical or buried deadman?
A vertical picket is fast to place, but the strength depends on the firmness of the snow. Here’s a quick rule of thumb to determine if the snow will hold a vertical picket, or if you need to take more time and make a T slot (deadman) anchor.
When placing a snow picket, a key decision is whether you can place it vertically (preferably leaning back about 25° from the direction of pull for optimum strength) or if you need to bury it as a deadman, a.k.a. T-slot.
If you're using it for crevasse rescue, where the anchor has to be unquestionably strong, a single T-slot or possibly a T-slot equalized with a vertical picket is usually the best choice.
In firm summer snow in ideal conditions, you might get away with a vertical placement, which is good because it's faster.
If you make a vertical placement, you get a much stronger anchor if you clip the picket in the middle instead of the top. From IFMGA certified guide Mark Smiley, on his Instagram, he writes:
“ . . . if the snow is soft enough to push one gloved finger into it, a top clipped picket will likely fail under 500 pounds (~2 kN) Yikes! A deadman style picket placed 60cm down = strength of midclip vertical pickets = ~1500 pounds (6.7 kN)”
(Side note: One of the best studies on snow anchors is from the 2010 International Snow Science Workshop, from a paper called “Snow anchors for Belaying and Rescue”, by Don Bogie (New Zealand) and Art Fortini, (USA). You can see it here.)
But if you're unsure of the firmness of the snow, here’s a good rule of thumb, also courtesy of Mark Smiley:
“Typically if it takes 10+ solid hammer strikes to drive the picket to the deepest hole (top of the picket), then I have confidence the snow is firm enough. If less than 10 strikes, I will switch to building a T-slot anchor...which takes longer to build but it’s stronger.”
Mark’s tip is in the comment section of this excellent Youtube video from Outdoor Research, “How to Build a Snow Anchor.”
Look at stream flow patterns to see elevation change
From a quick glance at stream patterns on a map, can you get a sense of where the high and the low elevations are? It's a helpful skill you can quickly learn.
Stream flow patterns on a topographic map can show you at a glance the higher elevations and lower elevations.
This map section below (from the US Geological Survey 7.5 minute map series) is in the Oregon coast range. Just by looking at the stream flow patterns (and without looking at the printed elevations (which are pretty darn hard to see anyway) can you tell where is the high ground and the low ground? And, for extra credit, what’s the lowest point on the map?
Here are a few ways to tell general map elevation from stream flow patterns.
A good starting assumption: water flows downhill. =^)
Smaller streams flow together to become larger ones.
When streams come together, they usually form a “V” shape. The two arms of the “V” point upstream, to higher ground. The tip of the “V” points downstream, to lower elevation terrain.
The origin of a stream on a map is called the “headwaters”. The stream always flows downhill from that point.
Contour lines always bend to point uphill when they cross a gully or drainage.
Let's look at a few examples.
When streams come together, they usually form a “V” shape. The two arms of the “V” point upstream, to higher ground. The tip of the “V” points downstream, to lower elevation terrain.
The origin of a stream on a map is called the headwaters. The stream always flows downhill from that point.
Contour lines always bend to point uphill when they cross a gully or drainage. (Look at the index contours, printed in bold every 5th contour line, they’re easier to see. Shown in red line below.)
So, when we put all that together, we see that Jordan Creek in the center is flowing from right to left (or east to west, if you prefer), being fed by various other creeks flowing from higher elevations.
Try this yourself. Go to Caltopo.com, zoom into a familiar area that has some streams, and see how all of these factors come into play.
And finally, because we know Jordan Creek is flowing from right to left (and because water flows downhill) the lowest point on the map is the one indicated below.
And as always, stream flow patterns, gullies, ridges and other landscape features are much easier to see when you use a map that has shaded relief. This is easily done in Caltopo for free. The map below has about 30% relief shading. Here’s a whole article on shaded relief, check it out!
If you are new to using Caltopo, it’s a wonderful mapping tool. I made a tutorial video on how to get started using it, you can watch that here.
CalTopo pro tip - split tracks, add colors and direction
On loop routes, it’s handy to use different line colors and/or styles to easily see the ascent and descent. This can be especially helpful when sharing your route with others who may not be familiar with it. CalTopo can do this easily with the “Split Here” feature.
(If you want to learn the basics of using CalTopo, start with this tutorial video.)
A more advanced tip in CalTopo (the best backcountry mapping software) is to “split” a track and give different legs a unique color and/or line style. Doing this shows at a glance the way up and the way down, and is especially helpful if you have a loop route on a climb or hike.
If the map is just for you, and you know the route, you probably don't need to do this. But if you want to share your route with others, doing this takes just a minute or two and makes the map much more usable for those who are not familiar with the route.
Here’s an example of the Mountaineers Route on Mt. Whitney in the California Sierra. What you’re seeing is a GPX track of the route (traced over to remove squiggles) downloaded from Peakbagger.com, which is a great source for finding GPX track files for climbing routes. We cover how to do that in this article.
Here's the entire route. The ascent route breaks off from the main climber’s trail a mile or so after the parking area, and proceeds counterclockwise. But, If you’re not familiar with the route, you wouldn’t know what’s the ascent and what’s the descent just by looking at this map.
So, let’s split the GPX track into two parts, the “up” part and the “down” part.
Zoom in close to the summit area, mouse over the line until it turns bold, select “Modify” > “Split Here”.
This splits the one line into two. The line still looks the same on the map, but if you look on the left side of your screen, now you should see two lines with the same name.
Now, let’s change the color. Click the “pencil” (aka Edit) icon next to the name under “Lines & Polygons” on the left side of your screen. Click the small red square in the edit box to choose a color. For this example, we’ll choose green for the ascent.
And, to clearly show the direction of travel, let’s change the line style to one with some directional arrows. To do this, click the “Pencil” edit icon again, and click the horizontal line that comes after “Style” in the edit dialog box.
Repeat this with the second line, choosing a blue line color and the same directional arrow.
Now, that’s an improvement! Someone seeing this map for the first time can immediately determine the ascent and descent. If you’re making a map for any kind of public sharing, even if it’s with some other teammates on your trip, taking an extra minute or so to do this makes your map more legible for everyone.
And finally, below is a screen grab of the PDF file of the map made from CalTopo, which prints nicely on 8.5” by 11” paper at 1:25,000 scale. Print this to use on your climb, and save it as a PDF on your phone as a backup. (The base map is USFS 2013, with about 20% shaded relief.)
Redirect the Grigri brake strand for extra friction
If you're using a Grigri or similar device on a top rope belay, and you have a heavy partner, small diameter, and/or wet/icy rope, sometimes you need additional friction. Here’s an easy way to do that - redirect the brake strand through a second carabiner.
When top rope belaying with a Grigri or similar auto locking belay device, you may find you need extra friction when lowering. This could be due to lowering a heavy partner, skinny rope, slippery rope sheath, wet/icy rope, cold hands, gloves, or some combination of the above.
One crafty way to do this is to redirect the brake strand through a second locking carabiner clipped to your belay loop.
You can use a normal locking carabiner to do this, or the more specialized (and expensive, and strange looking) Petzl Freino carabiner, which has a secondary “braking spur” designed specifically for rope redirect and extra friction when belaying or rappelling a single rope strand.
IMAGE: HTTPS://WWW.REI.COM/MEDIA/PRODUCT/716219
Like with all lowering techniques, the effectiveness of this depends greatly on the variables mentioned above: rope diameter, how slippery the sheath is, if the rope is wet / icy, weight of your partner, etc. Practice in a controlled environment before you try it in the real world.
Karsten posted two nice photos on his Instagram, which pretty much sums it up.
Method 1 - SOME extra friction - brake strand redirected through the gold locking carabiner.

Method 2 - a LOT of extra friction, with the brake strand redirected through the locking carabiner AND passed back over the Grigri.

New from CalTopo - high resolution slope angle shading
CalTopo, the best backcountry mapping software, just got even better. The slope angle shading is now at an even higher resolution, improving wilderness trip planning for much of the United States. See some examples here.
If you’re new to CalTopo and want to learn the basics, start with this tutorial video.
Note: this type of slope shading is made with an elevation model that may not show all relevant features and potentially hazardous avalanche slopes. It can be a useful tool for macro level trip planning, but is not accurate enough to completely assess potential avalanche hazard across all types of terrain.
Slope angle shading is a very cool feature of CalTopo, the best backcountry mapping software. It’s handy for lots of different reasons, and we cover them in detail in this article.
Canyoneers or photographers, looking for seldom-seen waterfalls?
Backcountry skiers, looking for a low angle ascent and a slightly steeper downhill?
Winter travellers looking to (hopefully) avoid avalanche slopes?
Cross country hikers or mountaineers, looking for the path of least resistance?
Slope angle shading can help in all of these situations. Now, the digital mapping data that underlie the slope model is improved, and the resulting shading is much higher resolution.
Here’s a comparison of the old and new slope angle shading, with the Disappointment Cleaver route (red line) on Mount Rainier. The top image is the older style shading, the bottom image is the newer one, using the higher resolution LIDAR data.
Pretty cool to see how the route picks it’s way up through the path of least resistance. You can use this feature to plan a cross country travel route in CalTopo for a place you've never visited! (Of course, glaciers can change on a daily basis and you should never fully rely on a model like this, but it’s a great start.)
Caveat: This new data set does not cover all of the United States, and is sadly lacking in many parts of the western US, but hopefully that will be improved in the next few years as additional LIDAR data are collected. See the data coverage map below. (Sorry Wyoming, Montana, and Sierra Nevada.) Good news, you are highly unlikely to be caught by an avalanche in Louisiana. =^)
Below is a copy/paste from the CalTopo website, Dec 20 2019.
http://caltopo.com/about/2019/12/20/high-resolution-elevation-data/
“CalTopo first launched the slope angle shading layer 7 years ago, and since then it has become a mainstay tool for backcountry trip planning. Today we're updating the layer to incorporate high-resolution LIDAR data from the USGS's 3DEP program. Where available (see coverage map), this provides significantly higher resolution, even allowing you to identify trails from relief shading. As additional coverage becomes available we will add it to this layer.
While the LIDAR data is very high resolution, it should still not be relied on as a definitive source of truth. Beyond possible errors or accuracy issues with the dataset or our processing of it, the surface angle on top of a snowpack may not match the bare-ground angle underneath. Carefully assess and evaluate any terrain that you are traveling in, and confirm your observations instead of relying solely on maps.
This update is now live on the web! It will be released soon on iOS and Android. Offering online access for free, and offline downloads with a CalTopo subscription. The significant increase in resolution means the offline downloads are larger in size than previous elevation data. Be cautious downloading using mobile data and storing on your phone, storage may go quickly.
As with previous expansions of the slope angle shading layer to Canada and Alaska, the high resolution dataset is not available to third party apps that license CalTopo's pre-rendered layers like Gaia GPS and Backcountry Navigator. You can only access the layer via CalTopo's website and app; we encourage you to download the new app to use this layer in the field.”
“Rock shoe rejuvenator” - rubbing alcohol
There's a quick and easy way to revive your rock shoe rubber - Give it a quick scrub with some rubbing alcohol (and maybe sandpaper.)
Rock climbers love that incredible stickiness from a brand new pair of rock shoes. But when dust, chalk, grime etc. get slowly ground into the rubber, it seems like you never quite get back the “grip-tion” of new shoes.
Well, you can, or at least get pretty close. Wipe down your shoe rubber some rubbing alcohol. Do this outside, as the fumes can be strong. A rag works better than paper towels.
Some gentle buffing with 80 grit sandpaper or a wire brush can help rough up the surface and make your shoes a bit stickier as well. Give it a try before your next hard boulder problem or red point attempt; every little bit of grip helps!
Safety for leader #2 on sport routes
If you’re leading a sport route at your limit, having the first bolt clipped increases your safety by eliminating a ground fall. With this simple rope trick, the first leader can pre-clip the first bolt for the second leader.
Heidi and Hans are out for a day of sport climbing, and they both want to lead all the pitches. They don’t have a stick clip. Heidi, being the stronger climber, feels fine with leading without the first bolt being clipped.
But Hans is leading at his limit. He wants to reduce his risk by having the first bolt clipped, eliminating any chance of a ground fall.
Here’s a simple way to do that, with the one caution that you need to have a bit of extra rope.
Say Heidi leads the route first. She climbs the route, clipping all the bolts, clips the anchor, and calls for a take and lower.
On her way down, she clips a quickdraw to her belay loop and to the rope running through the bolts; this is known in some circles as “tramming”. Doing this keeps her close to the rope and gear, which is especially helpful on traversing and/or overhanging routes.
Note the quickdraw clipped to the climber’s harness and the rope in this nice diagram from Petzl. Perfect tramming technique!
image: https://www.petzl.com/US/en/Sport/Recovering-quickdraws-in-an-overhang-while-descending
She calls for a brief take at each bolt and removes all the quickdraws, except the one on the lowest bolt.
When Heidi gets to the lowest quickdraw, she does not clean it, but instead keeps lowering to the ground. Doing this keeps the rope through the lowest quickdraw.
image: https://www.petzl.com/US/en/Sport/Recovering-quickdraws-in-an-overhang-while-descending
Heidi unties, but keeps the rope clipped through her quickdraw. Hans pulls the rope. The rope zings through the top anchor and falls to the ground, but now it’s clipped to the first bolt. This gives a “toprope” to the lowest bolt for Hans on his lead, with no chance of a ground fall.
Using this technique can be more helpful in climbing areas that often have hard moves right off the ground, or have first bolts that are especially high, or both. (Smith Rock, I'm looking at you!)
Using this “tramming” method guarantees that the rope end will fall to the ground, every time. If the route is fairly steep, without any ledges, shrubs, or anything else the rope may get hung up on, you can probably skip doing the tramming. Just leave the rope clipped to the first quick draw, have the belayer pull the rope, and the end should fall to the ground and stay clipped to the lowest bolt.
But keep in mind, if you do this, and the end of the rope does not cleanly fall to the ground, you're probably going to have to pull it through that lowest draw, and it won't be clipped anymore, which defeats the whole purpose.
Safety notes:
Caution #1: Doing this requires you have enough extra rope that is twice the distance from the ground to the first bolt. If your route is a real rope stretcher, or the first bolt is really high, this technique might not work.
Caution #2: The belayer should always be tied into the end of the rope, or at the very least have a knot in the end to have a “closed rope system”. This technique takes a bit of extra rope, and you definitely do not want to drop your leader. One more reason to get a 70 meter rope . . .
