Quick report
- Collapsing
- specific
Feedback (in the form of collapses that typically radiated 10 to 40 feet) required some hunting and stomping away from previously tracked areas. Another group in the area commented on how quiet the snowpack was. Remote triggered a very exciting D3 avalanche that connected across multiple start zones about 1800' wide. You'll just have to watch the video to appreciate this one.
Most of the tour, we traveled on an existing skin track without signs of instability. Once we got off the skin track, we produced occasional small to medium-sized collapses, almost all of which required a stomp or ski stab. A handful of these collapses were on flat slopes above a steep SE-facing start zone, and didn't produce any avalanches. As the start zone changed to east-facing, we had the same lack of activity for the first few collapses. I have about 5 minutes of footage of Eric walking and stomping along the ridge, getting excited about a collapse, but nothing happens. The final collapse on a less-gladed slope produced the big slide.Weather

Snow surfaces got wet on southerlies and there were a few minor wet loose avalanches from rocky slopes.

Remotely triggered a very large avalanche from a stomp near the summit ridgeline. The slide began as a D2 on an east-facing feature, hit the apron, and then connected into northeast and north-facing features, about 1800' wide. Where we triggered the slide from, the crown was about 2 feet deep, but it entrained the entire weak snowpack to the ground, which was 4 feet deep.
