Extremely widespread collapsing on all aspects. On the third lap up the same skin track we were still experiencing collapsing.

Avalanche

We skied down a slope just west of Ridgeline Yurt. When I got to the bottom i looked up at the slope across the drainage (to the west) I saw an avalanche start, at approximately 12:05. The debris moved pretty slow, and then propagated back up the slope and triggered 2 more slides on connected slopes. I quickly put skins on, skied over and did a beacon search, receiving no signal. Skinning back up the slope we skied down I could see there were no tracks going in to the path. Based on timing I think I remote triggered it. I was 120 meters from the toe of the debris when the slide started. The slide ran around 110m vertical (based on map, i did not skin to the crown), and the debris stopped about 20m up from the bottom of the slope. The thickest debris was around 50cm, but mostly less than that. Probably a D2.
