Recent Avalanches? | No |
Collapsing (Whumphing)? | Yes |
Cracking (Shooting cracks)? | Yes |
Went for a quick tour to check out the remote triggered avalanche near the road. Still thin coverage with snowpack offering little support. Bring your rock skis/board.

Human triggered avalanche reported yesterday. Several Avalanches on the S/SE face of Sky Scraper peak. When approaching crown of yesterday's avalanche, one small collapse and shooting cracks up to 15 feet in length were observed.
Broken sky, Light winds form the N, 32ºF. Trace new snow-some graupel and precip particles
Snow surface was low density decomposing snow from yesterdays snow fall.
The snowpack near yesterday's remote triggered avalanche is thin, has poor structure, low strength, and high propagation potential. The weak layer that failed in yesterday's avalanche was 2mm faceted snow that failed near the ground. Besides the obvious red flags(recent avalanches, cracking and collapsing) the Propagation Saw Test and Compression Test provided the most useful information from today's crown profile. The crust that has formed near the ground was present in the pit dug today, it was brittle and was not always easily found on the crown of the avalanche.
