From message 2/20/22: "Triggered this slide yesterday a few miles from two top. 1.5 foot crown."

Avalanche overview with the crown and path marked. The slide was 800' wide, 1200' vertical and averages 2 feet deep (estimated).

The toe of the debris was 1200' from the crown (marked). The debris was not wide (75-100') because it was constricted by the gully, but was estimated to be 15' deep. Photo: GNFAC

The rider was partially buried with his arm and airbag showing. His head was 1' under the surface but did not survive. He triggered it near the crown, 1200' higher and was funneled into a terrain trap that carried him over the waterfall/cliff in the background. Photo: GNFAC

The avalanche averaged an estimated 2' deep, 800' wide and 120' vertical. This left side of the crown was deepest wih an estimated 4' depth. Photo: GNFAC

We were able to trigger a couple small slabs of wind-drifted snow at the ridgeline of Divide Peak on 2/18/22. This is a sign recent drifts are unstable for a day or two. Some recently formed wind slabs could be large enough to bury or injure a person. Photo: GNFAC
