Partnered with Going-to-the-Sun Road forecaster to assess avalanche hazards from this weekend's storm, and do some janitoring at the Garden Wall weather station (image).
Dry snow avalanche hazards seemed confined to steep, upper-elevation slopes where winds have drifted and stiffened the new snow. These could run fast on the hard crust below. Direct sun on the new snow at upper elevations seems likely to trigger widespread dry loose snow avalanches. On steep, continuous avalanche paths where these could run below about 6000 feet, it seems they could gouge into the moist snow below the soft, near-surface crust and produce more dangerous amounts of debris.
Debris piles from fresh (since Friday) avalanches in 54-1 path, Birdwoman Basin, and Haystack Creek. D1.5-2. Couldn't see starts. Appeared to be rain-induced wet snow avalanches - probably loose - that ran during Saturday's upper-elevation rain event. Not a widespread cycle.
