Comments

We observed cracking, collapsing, and avalanches while skiing along the Park City ridgeline today. Fresh wind drifts on the lee of the ridge were particularly susceptible to being triggered remotely. I remotely triggered some very small (10' x 20' x 15") pockets and noticed where other skiers had triggered bigger avalanches. The ridgeline windslabs were touchy, but I also noticed avalanches that were triggered mid-slope where there was much less wind effect. The avalanches were on the smaller side and pockety, in part because the new snow slab lacks cohesion.

Comments

Two mid-slope slabs were remotely triggered by skiers who skied between the two avalanche paths
