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.

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