The last reported avalanche from the backcountry occurred on Wednesday where a skier remotely-triggered (that is, triggered the avalanche from a distance) a wind slab in
Radar Love Bowl, along the Park City Ridgeline, on a Northeast aspect at 9700’. This slab broke 18" deep and up to 125' wide, failing on the persistent weak layer down near the ground.
This heat map shows avalanche activity in the Salt Lake mountains since December 1, the onset of when we began to overload the persistent weak layer.
