The heavy precip rates last night, accompanied by a few hours of strong winds and warm temperatures rapidly added a slab on top of the density inversion within the storm snow that started yesterday. This mornings burst of snowfall with the cold front added a bit more weight.
We were getting collapses often while sticking to the ridge today. Once we reached areas where the collapses were connected to steeper slopes with a cohesive slab, we started remotely triggering avalanches. We remotely triggered 4 or 5 from distances of 60m to 110m away. Fractures were running wide, and averaged 40cm deep. Visibility was quite limited during the day, but with what little we could see it was apparent a widespread natural cycle had occurred.
Avy danger was High last night into this morning, then lowering into Considerable later.
