From obs: "The crown of the westward slide looked to be around 4'. Like the one reported the other day, it ran almost to the skin track. Winds were high in the basin and on the ridge tops, transporting snow into moderately stiff slabs." Photo: S. Lowe

Avalanche triggered on 01/19. From obs on 01/20: "Off the top on the face of Blackmore- Talked to the guy that set this slide off, it was triggered while he was skiing down yesterday (01/19) morning from the summit. Ran all the way down to almost the skin track." Photo: N. English

On 1/20 At the top of The Ramp/Wolverine I pushed on some small wind-loaded terrain features with skis. About three inches of soft snow moved/cracked no wider than my ski width, then one step lower a hard slab cracked out about 10' wide, 10-12" deep and did not move more than a few inches downhill due to flatter terrain supporting it below.

On Sawtelle Peak, Island Park, when the clouds lifted we could see a crown of a snowmobiler triggered slide that occurred yesterday. It broke on the buried surface hoar and facets about 1.5 feet under the surface. Recent snow and wind-loading has created dangerous avalanche conditions. Photo: GNFAC
