Awesome photo Steve. Did you guys at least have crampons?
@top rope happy:
Yes, that does work, I actually did that (once...) when descending a climb in Chamonix. We had done the North face of La Tour Ronde a classic moderate route, and were descending the SE ridge, still short-roped together. I was in front, and my rope mate stumbled off the side of the ridge at a pretty exposed spot. He yelled, and I looked over my shoulder, he was starting to roll, and I wasn't sure he was going to be able to arrest. Since he was behind me, I didn't think I could get myself set up in time to slow the fall. It was a really easy decision, and seemed to be made very quickly, I just hopped off the opposite side of the ridge and arrested about 5 feet below it. The rope dug down a little into snow on the ridge, I can't say I even felt any kind of a tug, but where we were was not super steep. Turns out the rope did actually stop him though, so I'm glad I did it, as he probably could have yanked me off with him. I climbed back up and poked my head over, and he was lying face down in the snow, cursing like a sailor because he was so jacked up on adrenalin, and super pissed at himself. He said, afterwards, that he tangled his feet with his crampons, and just tripped.
