Utah Avalanche Center

Snowmobile triggered avalanche on Saturday, March 12, 2022. This profile was recorded in the flank. Similar stratigraphy was seen nearby and on March 8. See snowpilot pit from that date (https://snowpilot.org/node/41581). In nearby pits we got ECTP15 on the same PWL.

Representative location in clearing in a place that is usually undisturbed. Probing with my ski pole handle, the same weak layer is quite widespread and consistent. I'm concerned about this layer as it consistently propagated with medium force.

Clear in the morning with increasing clouds and southerly winds ahead of a storm system tracking to the north. Spring conditions in full effect with all surfaces sun affected including low angle northerlies. Had planned to do an ECT but the slope collapsed while I was digging.

Fracture profile for skier triggered avalanche, 1 to 2' deep x ~400' wide, running ~300vrt'

There were at least two natural avalanches on the same aspect and elevation. Two collapses at this pit location with a crack in the pit wall.
