Weather
Mostly cloudy day, but with a few bits of sun and greenhousing. Winds picked up dramatically just after noon. Snow transport was visible across near and above treeline terrain throughout the Ruby Range for a few hours.
Snowpack
Experienced a few small, quiet collapses on drifty near treeline terrain. Dug a test profile adjacent to a remotely triggered avalanche. Slope that avalanched was around 38 degrees (measured from the side not on bed surface might be a bit steeper). Steep, previously drifted slopes remain a concern and seem sensitive to human triggering on the upper Persistent Slab interface. This interface will likely be a real concern with the incoming storm. Descended a 25-degree southeast-facing slope at about 10,400? feet that had dry surface snow….noticed a few rollerballs on a steep more southerly feature.
Avalanche
Remotely triggered a small, D1, avalanche on a steep east-facing slope at 11,100? with previous drifting.
