Rappel tips for tricky terrain
In most rappels, getting the rope down is pretty straightforward: give each strand a toss and hope for the best. However, challenging terrain and conditions may require some specialized techniques. Here are a few.

Note - This post discusses techniques and methods used in vertical rope work. If you do them wrong, you could die. Always practice vertical rope techniques under the supervision of an experienced climber, and ideally in a progression: from flat ground, to staircase, to vertical close to the ground before you ever try them in a real climbing situation.
The standard rappel practice of “toss-rope-with-a-knot-on-each-end-and-hope-for-the-best” usually works fine in friendly conditions.
But, if you have any one or combination of these potential rappel problems:
high winds
traversing and/or overhanging rappel
low angle
vegetation, deep cracks, or other rope eating features
then the typical rope toss might cause some issues.
Here are some alternative rappel methods for these difficult conditions. (Listed in my rough personal order of preference. )
Rope bomb
Lower your partner
Rope bag
Saddlebag
Tie both ends to your harness
Lower down both rope ends with a weight
Let's take a closer look at each one.
1 - The “rope bomb”
I wrote a detailed article about the benefits of “casting” your rope, like casting a fishing lure; a sort of weight on the end that spools off the rest of the line.
That's the idea here. Flake each half of the rope into two piles, then make a small butterfly coil with roughly 1/3 of the rope. This is the “weight”. Now, you can toss this with some force down the route, and with any luck this will carry down the remaining rope.
In my opinion, this is preferable almost all of the time! Instead of chucking off half of your rope in one big coil and hoping it's going to feed out smoothly, which it hardly ever does.

2 - Lower your partner
Everyone is fine with being lowered by their partner when top roping from the ground or in the gym. But for some reason, the technique is rarely used by recreational climbers when it comes to being lowered from above. (It's more common in a guided situation, especially with a partner who may not be comfortable rappelling on their own.)
However, with a little practice, it's perfectly safe to do, and can easily get the first person down along with both ends of the rope, no problem.
Attach the ends of both ropes to your belay loop, with either a tie in knot or locking carabiner, your choice. Your partner lowers you on one strand directly from the anchor.
To lower your partner, you can use one of several different methods: a redirected tube style belay device, a Grigri, or a Munter hitch.
Pros - pretty much guaranteed to get the rope down smoothly.
Cons - Potential communication issues if you can't see or hear each other. (Radios could be helpful.) Lowering someone past the anchor could cause some problems. Lowering from above is an unfamiliar technique for most folks and requires practice to do safely.
Here is a more detailed article I have on lowering your partner.
Here is one of several ways you can be lowered; with a Grigri. Note the redirected brake strand, this is important.
3 - Rope bag
Yes, my partner laughed at me, but I did bring a plastic grocery shopping bag on one climb where I knew we're gonna have some low angle rappels and it was pretty awesome. Trader Joe's shopping bags cost one dollar, are surprisingly sturdy, rolls up about the size of a burrito, weighs about 40 grams, and easily holds a 60 meter rope.
I never noticed it in my pack, but it made life a lot easier when we had to do multiple low angle raps. We flaked the rope into the bag (which took about two minutes) and then I hung it from my harness with a sling. The rope fed out beautifully.
Just because people don't do it very often doesn't mean it's a bad technique! (Personally, I found it easier than saddlebagging, which we’ll discuss next.)

Since I've been yapping about the book “Down” throughout this article, I thought I'd give it a more formal plug here. Andy Kirkpatrick's book is an outstanding deep dive into the topic that I think is helpful for most everybody who plays in the mountains.

Alpine retreat anchors - Part 2
Retreat (aka bail) anchors or not something you hopefully do very often. But when you need to, there are some specific requirements. See examples of strong and simple rigging here.

Always practice vertical rope techniques under the supervision of a qualified instructor, and ideally in a progression: from flat ground, to staircase, to vertical close to the ground before you ever try them in a real climbing situation.
The techniques shown below are NOT standard anchor building practice. For normal anchors, clip a carabiner to your gear placements before you clip the sling/cord. These examples are retreat anchors for bodyweight rappelling only, when you want to conserve your gear.
Be it challenging weather, poor conditions, route finding errors, or general loss of mojo (a.k.a. “ambition exceeding ability”), there can be lots of valid reasons to turn around on an alpine route. It may not be something you actively planned for, but it needs to be handled with the same level of focus and detail as any other part of your climb.
When you retreat / bail (and yes, it’s “when, and not “if”), be it a one pitch sport climb or a major alpine adventure, the objectives should be similar:
Get to the ground in one piece
Have each rappel anchor simple to build and easily strong enough to rappel on
Leave a minimum of gear behind
Let's be clear on one thing: this is no time to be a cheapskate. Yes, we hate to leave gear behind, but if you HAVE to leave your beloved #3 Camalot for a rappel anchor, then do it without hesitation. The simple question is, what's your life worth? At the same time, you don't want to over build your anchors, and leave behind gear that you might need lower down if multiple rappels are required.
What are the forces on the anchor when rappelling?
I recently came across a nice video from the meticulous gear testers at Edelrid. (Have a look at their “Edelrid Knowledge Base” on YouTube, they have lots of goodies there.)
Check out the screen grab below from one of their videos.
Short version:
If you bounce around on the rope like some special forces cowboy, you can generate between 2 and 3 kN as a temporary peak load.
When you rappel smoothly, the load to the anchor is pretty much your body weight.
Takeaway: rappel smoothly without bouncing to minimize force on the anchor.

There are lots of ways you can rig a retreat anchor. Here's a good one.
Simple (easy to check)
Fast to rig
Plenty strong enough for rappelling
Requires minimal gear
Place two pieces of solid gear fairly close to each other (here a stopper and a piton). Starting with about 2-3 meters of cord (here, 6 mm), pass the cord through both anchor points as shown.
Tie a flat overhand bend to make a loop.
Tighten the knot, leaving tails of at least 3 inches / 8 cm.
Pull down the cord, making a “U” shape.
Girth hitch masterpoint on a taped gate carabiner. (Lots of other options here. If you have enough cord, you can tie an overhand knot. If you want to use a quicklink or rappel ring, that works. I'm showing my favorite method to keep things consistent.)
This approach is fast, requires minimal fiddling with knots, and uses a small amount of cord. Efficient use of materials is the main benefit to the girth hitch master point.
Potential downside, you need to leave behind some hardware to make the girth hitch. (If you had another foot or so of cord, you could tie an overhand on a bight and rappel from that rather than the girth hitch.)
If you're new to the girth hitch master point, yes, it's legit and yes, it’s redundant. Read a more on the girth hitch anchor here.
What if the anchors are farther apart?
What if you want to use a sling instead of cord?
Tying a cord directly to a stopper wire? How strong is that?!

Alpine retreat anchors - Part 1
Retreat (aka bail) anchors need to be strong enough for a rappel, use a minimum of gear and cordage, and be simple to rig. Learn the principles here.

At the same time, you don't want to over build your anchors, and leave behind gear that you might need lower down if multiple rappels are required.
Alpinist Steve House has a terrific video on “Failing Well”. “Success on a climb is going up, making good decisions, and coming back. That's the outcome we should be attached to. To me, that’s what ‘fail well’ means.”
Six minute YouTube video, highly recommended. Takeaways:
Strategic retreat is an inherent part of alpine climbing. It’s a skill that improves with practice.
Having solid retreat technique can give you the confidence to try harder routes, knowing that you can retreat from just about anywhere.
Maintain awareness when ascending. The way up might also be the (unplanned) way down. Remember potential anchor points, problem areas and the right way to go.
Retreat is often done under stress, tiredness, darkness, bad weather, etc. All the more reason to turn up your focus and awareness to counter these compounding factors.
Some general guidelines for retreat anchors . . .
Use two equalized pieces whenever possible. Sure, the classic climbing books are full of epic stories of rapping off of a single stopper or piton. One that’s perfectly placed should be sufficiently strong, but that shouldn’t be your first choice unless things are really desperate.
Try to avoid using multiple pieces of the same size in a single anchor; you might need that same size lower down.
Use static equalization. This is probably not the time for a sliding X anchor. Your gear may not be the greatest, and there's only two pieces, so you want to minimize any potential shock loading at one piece fails.
This anchor is only for rappelling, so the “rules” change a bit. The belay anchor general principle of striving for “three good pieces“ doesn’t necessarily apply to a rappel anchor. If you rappel smoothly on a dynamic rope, the anchor will only see about 1-2 kN, and the direction of force will always be down. So good news, your anchor doesn’t need to be multi-directional or tremendously strong. However, we're still aiming for some other core anchor principles of strong (enough), redundant, load distribution, and no extension.
The examples below don’t use carabiners on the gear. You’d never make a proper belay anchor like this as regular practice, but it's acceptable for an emergency rappel anchor. It's fine to run cord or webbing through stopper wires for a rappel anchor; it holds 8+ kN. (See previous point, the rules change a bit.)
Rappel smoothly to minimize forces on your anchor. Don't jump / bounce around like some special forces cowboy.
Keep your rigging simple. You should really only need one or two variations on the basic theme, so no need to get overly fancy. You're probably going to be doing this under a bit of stress, and bailing on marginal anchors is not something most people practice very often. Keeping your rigging clean and simple makes it easier to check and to remember.
You're going to need a fair amount cordage (and maybe a few slings) so plan ahead. 6 mm cord (rated to about 7.5 kN) is cheap, light and easy to carry, so consider that if you anticipate making a lot of anchors. Tying those pesky knots always seems to take up more cord than you think! Plan on about 2.5 meters of cord per anchor. You can get away with a bit less if the gear placements are right next to each other, or if you use some clever knots like a girth hitch master point. If you and your partner each carry about 10 meters of cord, that's enough for a LOT of anchors.
Use your cordelette. Six meters or so of cord (7mm is the standard) makes a cordelette for the way up; you can think of that is equal to about 2-3 potential anchors for the way down. If you and your partner each carry a cordelette, together that should be good for about 5-6 anchors.
What about webbing? Tubular webbing can work as a retreat anchor, but it has a few downsides compared to cord. 1) Webbing strength drops off quickly if it gets damaged, unlike cord that has more of a protective sheath. 2) Webbing is more easily degraded by ultraviolet light. 3) Webbing usually requires tying a water knot, which can be a little finicky and a hassle to tie if you have gloves and/or cold fingers. For these reasons, cord is usually a better choice. (See an example below of how to use a sewn sling.)
Carry a knife, so you can cut up your cordage (or maybe even an end off your climbing rope) to make an anchor. Also, a knife is useful for cleaning up any rat nest of old sun-crusted cord and webbing you often find at alpine anchors. Good rule of thumb, if you add cord to improve an existing anchor, remove the oldest piece(s) and take it with you.
Don't have a knife? It’s remarkably easy to cut through rope or webbing with a small length of 2 or 3 mm cord. Tie a bight knot in each end, clip the loops to a pair of carabiners for handles, and then rapidly saw back-and-forth through the material that's under some tension. You’ll cut it through in a few seconds.
Look first for a tree or rock horn. Give it a good kick first to assess its strength. You can drape a sling or tied loop around this and use it for a rappel, with no gear left behind. Note: use caution with putting the rope directly around/over a tree or rock horn; the friction could make pulling the rope difficult or impossible. Using natural protection of course preserves your hardware.
Consider shorter rappels. Doing two shorter rappels, using natural protection is going to preserve more gear than one long one.
Look for fixed gear on the way up. Remember where it is; you might need it on the way down.
Be wary of the “bail trail”. Don't be tempted to depart from your route to go towards a retreat anchor that someone else has left. If your route description says “belay from the ledge”, and you see some sketchy looking stoppers equalized with a shoelace on terrain that looks clearly off route, that probably means it's a bail anchor and not a belay anchor intended for ascending.
Be on the lookout for down-climbable terrain, and consider the technique of “down leading”. Here, the first person raps single strand, places his gear on the way down, and clips the rope to the gear. The second person ties in to the end, down climbs, cleans the gear as they go, and is belayed by the person below. Here's an article on that technique.
Leave a cam if you have to. Yes, your life is worth it. If you have a perfect placement for a larger cam, versus fiddling around trying to equalize several different stoppers, go for the one cam and get the hell down, especially if you have multiple pitches to go and it's starting to rain, getting dark, etc.
Stoppers and a piton or two are good choices for retreat anchors. Stoppers are inexpensive, strong, easy to check if you have a good placement (well, the bigger ones, anyway) , easy to bounce test, and can be set in rock that’s dry, wet, icy, or muddy. If you have a ice tool hammer, feel free to use it to smack on the piton as well as the stopper. To weld in a piton or stopper, you can beat on it Neanderthal-style with a fist size rock (and maybe your nut tool). But a hammer is always going to be better. No one's going to be cleaning it, so don't be shy.
If you find a fixed piton, see if there’s a nearby stopper placement you can use to equalize the two pieces.
Are things getting pretty desperate? You can cut your rope and leave it if you need more material for the anchor. You can also fix your rope and do the last rappel on a single strand if you don't need the rope for anything else.
Pitons!
You don't wanna carry too much metal with you, but a knifeblade and a “Universal” piton can be great to leave behind for anchors.
