My 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.
