Avalanche Details

Looked like a wind slab originated just below the ridge and maybe pulled out a deeper slab mid slope. We saw a few different avalanches today but this appeared to be most recent. Other debris piles looked like wet slabs in large complex terrain running to the Valley floor. Likely from the rain/ warming event last week.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Sun glorious sun! Gap winds cranking from WNW on the high ridges. Definitely moving snow but we found plenty of areas protected from the wind.

Snow surface

4-6” soft snow on supportable crust below ~500. Crust disappears with elevation and surface varies from 8-12” soft snow to stiff wind slab. No sun effect observed.


No formal snowpits. Jumped on some small, steep wind loaded slopes in low and mid elevations with no results. Progressed into steeper and higher elevation terrain through the day without incident. Fun day in the sun!
