Collapsing around Cooke City

Collapsing around Cooke City

Date
Activity
Skiing

We skied onto the debris of the Henderson Mountain avalanche. It went as wide as it could and broke under the dense wind slab on facets (not surface hoar). We dug in the flank at about 10,100' to confirm that it released on facets under a wind slab. Afterward we skied over to Daisy Pass and had numerous large, thunderous whumps, both there and back. At Daisy Pass/Chimney Rock avalanche (from 1/25) we had poor visibility and could not see the debris or paths. I skied out looking for signs, but decided that wandering in runout zones with no visibility was a bad idea, so we returned back to the sleds on Henderson Bench.
