Quick report
Sunny skies, 15-20°F, 30+mph W wind in the morning, calming to 5-10mph in the afternoon. Saw alot of big cornices on easterly aspects, above treeline. Dug a pit on the north side of bridger peak. E/NE aspect, approx. 10600', 23° slope angle Total HS 330cm, top 160cm was evaluated. CTM3 SC @ 130cm, CTM5 SC @ 120cm, CTH5 SC @ 73cm. ECTN18 SC @ 120cm. Overall, the snowpack density was consistent, top 35cm was fist/4F, over 1F (35cm-90cm), over pencil (90cm-160cm). Snow grains were rounded and forming chains throughout. No variable density changes or faceting was identified in top 160cm of snowpack.
Avalanche
E/SE aspect, approx. 10600', R2 D2 Wide propagation of a wind slab (right side of picture). Also, cornice appeared to break (top left of picture) and sympathetically release below. Assuming it all occurred simultaneously. Crown varied from 8-10 ft at the cornice, 2-4ft across the right side of picture. Tracks were observed and avy was likely triggered remotely from the ridge top on the same day as observation (2/24). Debris pile was still very soft.
