Though I'm still banking on a couple more big March/April dumps, it seems like spring has sprung and people may be headed out onto glaciated terrain.

There are a bunch of crevasse rescue videos available and this one seemed like one of the best. I took a half-day ropes and crevasse rescue course earlier this season and the biggest thing I learned was that I had a lot to learn. If you are not already aware and practiced in what to do if your bud drops down a hole, you can use this video as a springboard to learn more and train more. 

In some ways, avalanche rescue seems simpler than this—but likely with more fatalities. I hope you find this informative.
