From email on 03/03/2024: "Two big avalanches observed above the “plug” east of Cooke city. on my ride over this AM. One ran to the road, unclear if it went over it and maybe the groomer ran over the debris. Appear natural or possibly snowmo triggered? "

Remotely Triggered Avalanche in Absaroka-BTooths

Date
Activity
Skiing

Remotely triggered a large avalanche on a N aspect at 9500 ft while ascending a ridge line [in Mill Creek, Absaroka]. We estimated the slide to be D3 R3. The crown spanned roughly 1400ft +/- and ranged between roughly 1-5ft deep. They appeared to be 2 distinct layers in the crown profile, one of recent ‘storm’ snow and a lower one above old facets. This was observed from a distance. Witnessed large trees being shaken by the slide and smaller ones completely breaking. The bottom of the run out became much more planar indicating the sheer volume of debris that filled in. Extremely powerful to witness such energy and destruction. All persons in the party were in safe terrain with no intention to ski this slope at all.
