Alpine Tips
What are oval carabiners good for?
Do you think oval carabiners look chunky and old school? Well maybe, if that’s your entire rack. But, for some specialized uses, they still deserve a place on your harness.

An oval carabiner was the first shape that was widely available to modern recreational climbers. However, carabiner design has changed a lot over the years, and now we have LOTS of different styles.
Does that mean the oval is obsolete? Nope! They’re great in certain applications.
Why are oval carabiners useful?
Behaves nicely with boxy devices like a Petzl Tibloc or Micro Traxion, or a fixed gate pulley
Perfect for racking stoppers. The stoppers rotate nicely around the oval end, and don't get jammed up like they can on a D shaped carabiner.
Works well with a Grigri and other types of assisted braking devices (ABDs), generally avoiding cross loading.
Tie a Munter hitch on them, and the hitch flips nicely back-and-forth. (That's right, you don't need a pear-shaped HMS carabiner for a Munter hitch.)
Rotates through loaded anchors, pitons, clove hitches, and other attachment points; doing this can be a problem with some D / asymmetric carabiners.
If ovals are three-way loaded, they retain almost full strength, (tested up to about a 60 degree angle), see video below.
Great for aid climbing, when you often have more than one carabiner clipped to another.
Works nicely as a top rope master point, using three snapgate ovals opposite and opposed. Functionally the same as two lockers, gives a nice smooth lower, and maybe puts the wear and tear on less expensive ovals instead of your more $$ locking carabiners. Here's how to set that up.
Reasonably lightweight; about 60 grams.
Fairly inexpensive, compared to other specialized lockers.

Big load on a bight knot? Try a butterfly
Is your bight knot going to take a BIG load? Consider using a butterfly instead of a figure 8 or an overhand. The butterfly is usually a lot easier to untie after it takes a heavy load.
There are three bight knots commonly used in climbing:
overhand
figure 8
butterfly
(Yep, I'm calling it a butterfly, and not an “alpine” butterfly. I don't see any need for the word “alpine”, and I like simplicity.)
If you're putting any significant load onto this knot, consider using the butterfly.
It's usually much easier to untie after being loaded than the other two, with the overhand usually being the most difficult. (Most big wall climbers, who regularly deal with heavily loaded knots, have known this trick for a long time.) In the photo below, we have a figure 8 on the pig, because that’s pretty much a permanent knot in your haul rope that stays there all the time.
Of course, “hard” or “easy” is subjective! Factors such as your finger strength, level of patience, whether your rope is old and crusty or new and slick, wet or dry, can all have an effect.
What about a bowline?
A bowline is also easy to untie after being loaded. However, it has a tendency to loosen if it's subject to repeated loading and unloading, and it also needs some sort of backup. Also, it's tricky to tie as a bight knot in the middle of the rope, as we're doing here.
So, in most recreational climbing applications, one of the three bight knots listed above is usually preferred.
Electromagnetic interference (EMI) and avy transceivers, from BD
Black Diamond published a very interesting study about the effects of common electronic devices and how they generally do not play well with avalanche transceivers. Here’s a link to their excellent article.
In January 2024, Black Diamond published an interesting study about how different electronic devices that we might carry in the mountains affect avalanche transceivers.
It's definitely worth a read. From their blog post:
“Various electronics often found in the backcountry were used in our test, including smart watches, GPS watches, smartphones, two-way radios, action cameras, satellite communication devices, electronic airbag packs, and even a snowmobile. The searching transceiver was held at 50cm from the torso using a static tether to help maintain the appropriate distance. Each item was then placed in a normal use position as noted below.
The goal was to determine how bad it might be to violate the 20/50 rule. To do so, many items were held closer than 50cm (i.e., heated gloves and smart watches). Each item was tested three times, and the average taken. We then calculated the reduction in range compared to a baseline with no other items present.”
“The takeaway here is that EMI is real, and it can have a significant impact on transceiver performance! And we can’t stress enough the importance of updating the firmware of your avalanche transceivers and electronic avalanche airbag packs.”
Don't pre-rig a rappel with a Grigri on top
The always terrific Petzl website has a specific caution against a pre-rigged rappel with a Grigri on top. Apparently, when the rope is loaded from below, occasional device failure can happen for the person above. Good news: there are some easy ways to eliminate this problem.
The pre-rigged (aka “stacked”) rappel, is a technique where both partners rig their rappel device at the same time, usually with an extension. Here's a complete article on it. A pre-rigged rappel increases efficiency and (usually) reduces risk.
Increases efficiency: the moment the first person is down the second person can start.
(Usually) reduces risk: the last person gets a safety check.
However, there’s apparently an unusual situation where this might actually increase risk: when the top climber has a Grigri.
The Petzl website awards this a skull and crossbones, which always gets my full attention!
I’d never heard of this until recently (Dec. 2023) , so I want to give it a shout as a potential issue. Thanks to Alpinesavvy fan @timmyycedar for mentioning this to mementioning this to me.
Check out the diagram below from the (always awesome) Petzl website.
The example from Petzl, and the one I show here, uses two Grigris. But it seems to me that the exact problem would still be present no matter what type of device the lower person is using.
Also, there’s no mention of rope diameter. It also seems to me that a smaller diameter rope might be more prone to this problem, I really don't know.
Here’s the caution from Petzl against doing a stacked rappel with certain flavors of the Grigri (bold text mine).
“With the GRIGRI + from 2017 and on, and the GRIGRI from 2019 and on, unblocking and a consequent fall can occur if the rope is heavily loaded below the user. Unblocking can occur if the rope is loaded with a weight equal to or greater than that of the person rappelling on the GRIGRI.
Examples of dangerous situations:
Multiple people rappelling in sequence, GRIGRIs pre-installed on the rope. If the person waiting in turn to rappel has their GRIGRI pre-installed on the rope, it can be inverted (and thus unblocked) by the weight of the person rappelling below them. So it will not be operational when the second person wants to start their rappel.
Bottom belay: the person performing the belay maneuver must not hang on the rope.
Rescue from below: The rescuer must not ascend the rope of a person who is stuck on rappel.”
IMAGE: HTTPS://WWW.PETZL.COM/US/EN/SPORT/RAPPELLING-WITH-THE-GRIGRI?PRODUCTNAME=GRIGRI-PLUS
Apparently there are two other situations that can also cause Grigri failure. Check out the diagram below.
On the left, if someone gives an overly enthusiastic “firefighter belay” by putting their full weight on the rope, apparently that may cause Grigri failure.
Related to this, if someone is stuck on rappel and the climber at the bottom wants to ascend the rope, putting their full weight on it may cause Grigri failure.
IMAGE: HTTPS://WWW.PETZL.COM/US/EN/SPORT/RAPPELLING-WITH-THE-GRIGRI?PRODUCTNAME=GRIGRI-PLUS
OK, that's the doom and gloom stuff. Let's look at some simple ways to avoid this problem.
First off, this really only applies to descending a single strand of rope. It's pretty rare to do this in a normal climbing situation, so most people will never encounter this set up to begin with.
If one partner has a tube style device: set up your pre-rigged rappel so the first person down is always on the Grigri, and anyone else going down uses a tube device.
There are various other benefits for the first person down to use a Grigri, such as hands-free rope detangling, doing a pendulum if needed to reach an anchor off to the side, easily ascending the rope if needed, etc. Now we have one more reason to use this method.
If you MUST rappel single strand with two Grigris, there are other solutions.
Don't do a pre-rigged rappel, Easy!
If you do pre-rig, you can tie the rope to the anchor with a clove hitch (blue carabiner) , as shown below. This means the weight of rappeler #1 goes on the anchor, and not onto rappeler #2. This eliminate any chance of Grigri failure. Rappeler #2 removes the clove, cleans the blue carabiner, and rappels.
Here is a video clip showing how the failure actually happens. This was sent to me by @govanathon, thanks!
(Actual failure / device inversion starts about 1:50.)
Quad anchor - 240 cm sling with bowline on a bight
If you have a 240 cm length sling, it can be annoyingly long to use on a two bolt anchor, especially rigged as a quad. Here is a clever way to rig it so your master point is high, and it's very easy to untie after loading: tie it with a bowline on a bight.
The standard quad anchor works great for many anchor setups where you have two reliable bolts or ice screws. Why is the quad cool?
Good load distribution
Minimal extension
Fully redundant
Quick to set up and break down; no knots to untie at each anchor
Super strong (would you believe 40+ kN?!)
Two independent and load distributed master points, which can be very handy
To make a quad, you have several options of materials and length. The original material, suggested by John Long in his book “Climbing Anchors”, was a cordelette. While there's nothing inherently wrong with this, it is big and bulky.
Modern sewn slings are a better choice. There are three lengths you could use for a quad: 120 cm, 180 cm, and 240 cm.
120 cm: too short, unless the anchors are very close to each other.
180 cm: the ideal for most cases, not too short and not too long.
240 cm: tied in a standard configuration is usually too long, putting the master point down low by your waist instead of up by your chest.
However, a 240 cm sling is a very handy piece of gear for lots of other things, and many people choose to carry that instead of a cordelette. You can sling it around a tree, you can equalize multi piece gear anchors, and if you use the clever rigging method shown here, it works great for a pair of bolts.
Rather than the standard method of tying an overhand or figure 8 on a bight to make your loops, instead tie a bowline on a bight. Advantages:
It uses up more material, which usually gives you a higher and more ergonomic master point. In the photo above, notice there are four strands on each anchor carabiner rather than the typical two.
A bowline on a bight is much easier to untie after loading, so at the end of the day you can easily untie your sling and give the material a rest.
This isn’t a standard climbing knot, but it's easy to tie once you get the hang of it. Here's a nice video that shows one way to do it.
A strong, simple and fast snow anchor
The T slot (aka deadman) anchor is usually a good choice when building a crevasse rescue anchor in snow. Here’s a quick enhancement that can double the strength.
Disclaimer: There is WIDE variability in the strength of snow anchors, due to factors like depth of the anchor, what you’re using for the deadman, temperature and water content of the snow, whether you stomp down (aka work harden) the snow between the anchor and the load, etc. A certain snow anchor flavor that tests to a certain strength in one location does not mean that result applies everywhere.
If you carry a picket, you have various options for building a snow anchor. With a very hard snow you can maybe use a vertical picket top clipped. With medium to hard snow, a vertical mid clip picket can work.
However, with softer snow, or if you choose not to carry a picket, about your only option is the “T slot” (aka deadman) anchor. This anchor can be made with gear like an buried ice axe, skis, or a backpack.
Here’s a way to (maybe?) double the strength of the T slot anchor, with a few seconds of work and one additional piece of gear: Add a vertical reinforcing placement to the horizontal placement.
image (used with permission) : https://www.vdiffclimbing.com/glacier-travel-snow-anchors/
This does a couple of good things:
It makes the horizontal placement much harder to pull out.
If the horizontal placement, like an ice axe, shifts a little bit under load, it can prevent the clove hitch (that's on the horizontal axe) from slipping.
(If you use a picket and girth hitch the middle hole for the horizontal piece, you don't have to worry about the connection point slipping.)
The typical method to beef up a snow anchor is to build an entirely separate one, and try to connect / equalize them with cord. This is certainly effective, but it can take a lot more time and gear (more cord and carabiners) to build, and will probably end up pretty much the same strength as this one.
Sounds good. How strong is it?
My pal Ryan Jenks at HowNOT2.com tested this. He got about 8 kN, which is pretty impressive! Compare this to a single horizontal buried picket, which he tested at about 4 kN.
Adding the vertical picket to reinforce the horizontal one pretty much doubled the strength of the anchor, at least in this one test.
Keep in mind this was in high water content snow in the Washington Cascades. This usually conpacts very well and make some reasonably strong anchors. Your mileage may vary.
Keep in mind that a typical crevasse rescue anchor will only need to hold less than the weight of the victim when they’re hanging. (The friction of the rope passing through the snow reduces the load on the anchor.) When hauling with a 2:1, if the pull strand is not redirected, the anchor should see about 2–3 kN at most. So, in the typical crevasse rescue scenario, loads on the anchor usually are fairly low which is a good thing.
I’ve seen quite a few studies of the strength of horizontal deadman anchors, but this is the only one that adds the vertical element. If anyone knows of other studies, please email me; I’d like to add those to this article.
A few snow anchor testing resources . . .
Here's a link to the British mountain rescue magazine from (I think) 2018. They got results that were different. Like I said, your mileage may vary.
If you really want to nerd out on snow anchors, here’s a webpage that summarizes most of the publicly available studies.
HowNOT2 video showing snow anchor pull test results. Horizontal picket about 6:00. Reinforced horizontal picket, about 6:35.
Screen grab from the above video, setting up the reinforced picket.
Finally, for a very deep dive into snow anchors, here is a nice presentation from the Mountain Rescue Association featuring snow anchor expert Art Fortini.

Kyle is a master at sewing and designing. He strives to use as much recycled and repurposed material as possible, such as extra sturdy sailboat sails.
HMG’s most innovative gear is the Taco portaledge system, the lightest portaledge (and fly!) currently available. Kyle was nice enough to send me one for review, and it's quite amazing. It's a sort of envelope into which you insert a Thermarest-style inflatable sleeping pad, and it's surprisingly comfortable.
High Mountain Gear also makes rope bags, which is pretty much mandatory to keep 6 mm tagline tangle-free. What I really like about his rope bags is the stiffness of the fabric, which keeps the mouth of the bag wide open when you're stuffing the rope, a big timesaver.
Related to the rope bag is the HMG ice screw cannon, a great way to store all of your screws and without them gouging anything else in your pack.
The Ski Guide Sled Tarp is an emergency shelter, and a way that you can hopefully drag out your injured partner if needed. Hopefully you don't need it for either one but if you do, you'll be glad you have it.

It may appear that it's a drawing program. But the real power under the hood is the ability to specify load and pulling forces to see how your system actually behaves in the real world.
They have a nice series of tutorial videos showing how to use every part of the software.
The “Getting Started” video is a good overview, to see if it's right for you.
I use vRigger in two main ways:
Setting up different mechanical advantage hauling systems to see the efficiency and forces anywhere in the system.
General purpose drawing and diagrams relating to rigging.
You can insert carabiners, pulleys, rope grabs, friction hitches, etc. to build just about any kind of rigging or hauling system you can dream of. They have a large “library” of pretty much every sort of rigging device available. (And, if they don't have the exact piece that you need, you can create it yourself.)
Drag one component on top of another, and they auto-magically snap together to build your system.
For example, here's a diagram that I made for an article on the three types of mechanical advantage (illustrating that a theoretical 2:1 will always be less in the real world, because of friction, rope stretch, and other hard to quantify variables.)
This shows the difference in efficiency in a 2:1 haul system, between using a pulley on the left and a carabiner on the right.
After you specify the weight of the load (here 100 kg, you can use ‘Merican freedom units as well) it automatically calculates the forces involved all throughout the system, depending on the rigging and load! Cool!
An interesting take away from this diagram: using a lower friction pulley is more efficient to move the load, but it also puts a higher load on the anchor. It's one thing to read about this in a theoretical way; it's another to see the actual numbers like this.
Here's something all climbers should know about: how changing the angles of your anchor “arms” can change forces on the anchor. These numbers dynamically update and change as you click and drag the anchor around.
Hint, you should never build a climbing anchor like this! You can see that there's no more load sharing, but in fact load magnification. If you ever make a Tyrolean traverse, be sure the anchors on either side are unquestionably strong, because they're gonna get a big load!

It’s not all engineering stuff. You can make more general purpose diagrams like this. Click and drag on the points and lines to create bends in the rope.

There is a very convenient section of “sample files”, which are essentially premade diagrams for common rigging. This is a big timesaver. Here's an example, some typical mechanical advantage set ups.
There are even gear libraries for specialized applications such as industrial, rope access and theatrical.
So, that's a quick overview of vRigger. While I’m only using a small portion of the capabilities, hopefully you get a sense of how helpful is it for visualizing, drawing, and determining forces of different rigging systems.

Grivel Clepsydra S - the best carabiner for glacier travel?
For glacier travel, it's usually best practice to clip, not tie, to the rope. The Grivel Clepsydra carabiner just might be the best tool for the job: the twin gates will never freeze or jangle open, and the keeper gate prevents cross loading. Plus, it has a bonus feature as part of a minimalist hauling system.
The Grivel Clepsydra is a very unique carabiner. It has a few features that make it perfect as your clip-in for glacier travel. (It comes in two sizes; here I’m featuring the small (S).)
Why is the Clepsydra S great for glacier travel?
No chance of cross loading means you only need one carabiner to clip to the rope
Unique Grivel twin gate means it’s always secure, can’t freeze shut, and can’t wiggle open during a day of glacier tromping. (Yes, the twin gate takes a little getting used to, but you'll figure it out.)
You can use the small end as a prusik-tender in a hauling system (photo below)
Small, fairly lightweight
When you’re not glacier climbing, it works perfectly with a Grigri, as the little “horn” prevents the carabiner from being cross loaded
The standard recommendation for clipping to the rope for glacier travel is to have two opposite and opposed carabiners, at least one of them locking. With the Clepsydra, you only need one.
Before I got this carabiner, I used the Black Diamond Gridlock. This works pretty well, but the screwgate can loosen up over a day, plus as an HMS carabiner, it’s larger than necessary.
Here's how to use the Clepsydra as a “prusik minder” in a hauling system. The small end of the Clepsydra keeps the prusik hitch from being pulled through.
My crevasse rescue gear
There are many approaches to crevasse rescue and many choices for what gear to bring. You need light weight, multifunction, and hopefully have teammates with similar kit to have an effective rescue. Here's my go-to crevasse rescue gear.
There are many different approaches to crevasse rescue, and a near infinite combination of gear that you could carry. The basic requirements are 1) being able to climb the rope if you fall in, and 2) rescuing your partner if you’re the lucky one on top, and they can’t climb out. Fortunately, modern tools and techniques lets you do both with a minimum of gear and weight.
The gear requirements can change depending on team size and general skill level, but here’s a pretty good starting point.
This is pretty much the bare minimum. The idea is with a three of four person team, if everyone carries more or less the same basic kit, rescuers can combine gear as needed.
If you're on a two person team (which is generally considered experts only) you might want to carry a few more items, like maybe another locker, or a120 cm sling.
My crevasse rescue gear
6 locking carabiners: Grivel Clepsydra S, Black Diamond oval, large HMS and three “D” - The Clepsydra works great to clip yourself to the rope, because you can never crossload it, and the gate is very secure. Also works as a progress capture with a a prusik, if you don't have any progress capture pulley like a Traxion. The oval locking carabiner is a time-tested workhorse, and plays well with devices like the Traxion and Tibloc. A larger HMS locking carabiner is helpful if you need to clip other things to it. Finally the D lockers covers any other secure connection you might need. (Yes, I probably have one more locker than I need, but Murphy's Law of rescues is you always need one more locking carabiner.)
1 small snapgate carabiner - you need to rack your screw on something. You can use a non-locking carabiner for non-critical connections, such as the “tractor” in a 3:1 Z drag.
Petzl Tibloc - handy and lightweight ascender and rope grab.
Petzl Nano Traxion (or Micro Traxion) - the modern standard for crevasse rescue gear. Yes, they are expensive, but so helpful in so many situations, they are pretty much becoming everyday carry.
17 cm aluminum Petzl Laser Speed Light ice screw - if you can get down to ice, this can be your anchor on the top. If you fall in, you might be able to place the screw and clip yourself to it to take your weight off of the rope, which can make life for your partners on top a LOT easier when they set up the rescue. Don't bring a screw shorter than about 16 cm.
About 3 meters of Sterling V-TX cord - typically used for equalizing a second anchor, ascending a rope, or securing yourself to the rope system. (Amazing cord; 5.4 mm and rated 15 kN). You don’t need the standard (7 mm 6 meters long) cordelette on a glacier.
Short friction hitch - for climbing up the rope if you fall in, and for making a “tractor” on your hauling system. Here I’m using a spliced eye 5mm hitch cord, which grips well on 6 mm rope. This is made by a cool company called RopeLite; check ‘em out for custom spliced ropework solutions. (There are many other options, such as a loop of 6mm cord or a Sterling Hollowblock.)
What about that picket? Pickets can be very helpful in building a snow anchor but they're not required. Pickets are commonly carried in North America, South America and New Zealand, but not so much in Europe. A more minimalist approach involves making a T-slot anchor with your buried ice axe, skis, or backpack. But to me the axe is a crucial piece of gear, and I'm not too excited to bury it in the snow in case I need it for something else.
When I do carry one, it's the SMC Pro Picket. This is reasonably lightweight, has a pointy end for going into the snow and a reinforced top for bashing on with a hammer. The nicest feature is a permanently attached metal cable on the middle hole, which is how pickets have maximum strength in either vertical or horizontal placements. (That means you need one less 120 cm sling.)
What I don’t bring: pulley, belay device, several “just in case” extra carabiners, designated waist or leg prusik loops. Need another pulley? Grab the Traxion from your partner. Need to rappel or give someone a belay? Use a Munter hitch on your HMS carabiner. The carabiners above are more than enough. And forget those old-school designated waist and leg prusiks; you can easily ascend a rope with the gear shown above.
Where to carry this gear? You want the gear you need to climb a rope easily accessible on your harness or pack gear loops, not inside your pack. For ascending a rope with the gear shown here, I’d keep the orange cord and the oval carabiner with the Tibloc and the Traxion on my harness at a minimum. The rest can probably go inside your pack. I’d also keep the screw on my harness. If you fall in, you might be able to place it and clip to it, removing your weight from the rope as mentioned above.
Harness: A minimalist mountaineering harness, I like the Petzl Tour. Leave that sport climbing harness with the five gear loops at home. You want lightweight, no padding because you have on lots of clothes and (hopefully) are not gonna be hanging in it, with leg loops that open so you can easily put it on while wearing crampons or skis.
Rope: Varies on team size and skill level. Good options include:
30 meter, 6 mm Petzl RADline
40 meter, 7.7 mm Sterling Dyad
50 meter, 7.1 mm Edelrid Skimmer (which is currently the lightest dynamic rope on the market)
The diameter, length, and static vs. dynamic issue of the “best” rope for glacier travel is a BIG topic. Here's a link to some articles on my website that take a closer look. 1) Petzl 6mm static RADLine, 2) static rope for glacier travel.
So, that's my kit. Simple, lightweight, everything has a function. With this I can build just about any flavor of mechanical advantage hauling system I might need, like a 2:1, 3:1, and 6:1.
Some examples of 6:1 systems are here.
Minus the picket, this is what everything weighs.
Use the "Alpine Handrail" for a better bivy
The alpine bivy - like camping, only different! If you're spending the night on a small-ish ledge, here's a great way to secure both yourself and your gear.
Credit for this tip: blog post from Andy Kirkpatrick, shared with permission.
If you're spending the night at an exposed ledge, you hopefully have some room to move around and also to organize your gear. You want to do both without any concerns of falling off or dropping anything.
One solution: the “alpine handrail”.
Build a second anchor off to one side of your ledge away from the main anchor. It's ideal if these anchors are bolts. If not, be sure the anchor can take a sideways pull.
Tie a B I G figure 8 on a bight with a loop that's big enough to reach both anchors. In the photo I'm using a cordelette. On a larger ledge, use your climbing rope. Or tie two cordelettes together; get creative.
Tie two additional knots, and clip those to each anchor. In the photo on the left we have a clove hitch, which makes it easier to tension in the top strand.
Now you've made a sort of two story handrail. Make the upper rail fairly tight and the bottom one looser.
Use the upper rail to clip yourself with a tether, and the bottom rail to clip all your gear. You can move along the top rail without having to unclip to move past anything (other than your partner).
Because you made a loop, if any anchor fails, everything won't slip off of one end of the rope.
But what about that horizontal rope strand on the top? Doesn't that make sort of an American Death Triangle (ADT) / vector pull, maybe putting a large load on the anchors?
Excellent question! Short answer is yes, it kind of does, but it should not be a concern if you're on a reasonably sized ledge. That top strand is only if you make a careless stumble, or to keep you stable when you're sleeping.
If you are at a full hanging belay, where you’re putting a real load on the anchor all the time, you want to have a more typical anchor with a distributed load, NOT like this.
Besides, the so-called “death triangle” is probably not as bad as you think. Here's a whole article on it.
Extra points for using your climbing glove as a secure spot to hold your well-earned canned beverage. =^)
Double rope rap: clip tether carabiner to the “pull” strand
“Dang it, which rope strand do we need to pull, I forgot!” Here's a simple way to remember. As you start your double rope rappel, clip your tether carabiner to the rope that needs to get pulled.
For a double rope rap, of course it’s super important to pull the side that has the knot!
Nine times out of ten, you’ll be able to remember just fine. But for multipitch rappels, when you’re threading the lower anchor before pulling and swapping the rope that gets pulled every time, it’s dark, you’re tired after a big day, the weather is challenging, adrenaline-induced brain shrinkage, or whatever, this tip gives you one less thing to pay attention to.
After you unclip your tether carabiner from the anchor, clip it onto the rope that needs to get pulled (here, that’s green).
The carabiner politely slides down the rope above your device. At the bottom, there’s no question about which rope needs to get pulled; it’s always the one with your tether carabiner.
This isn't just for the last person. If the first person down does this, they can start threading the correct pull rope through the lower anchor.
Note: in the photo, I decided to not show a rappel extension to more easily see the rigging. Typically I use a rappel extension and third hand back up.
