Just finished the glacier section of the approach, was still roped up. About 10m into the rock section, a rock collapsed out from under me and I fell down the hole. Rope went tight. Arm got trapped under a rock and a guide, their client and my partner heaved it off me. The Guide short-roped us both back the short few steps to the glacier/safe ground. Got off amazingly scot-free given the potential, whole arm is bruised but not broken and got a scrape on my knee. Rotator cuff sprain. Walked off back to the Torino hut and got the lift down with partner carrying most of my pack.

Good weather - still, sunny day. Both participants experienced climbers and mountaineers, within grade and on familiar terrain.
