Remote Trigger in Mill Creek, Absaroka Range
Skiers in Mill Creek triggered an avalanche from 20' away from low-angle terrain.
From obs: "We were ascending a low angle shoulder when a NE facing slope around 20ft away went. Crown was around 2ft deep on both sides and around 4ft at the deepest. It broke on the layer of December facts with a pencil hard slab around 1ft-2ft thick. Above the older slab was new snow about 1ft deep in non wind loaded areas, and around 2ft deep in wind loaded areas. It ran about 300ft and was 50ft wide. "
