Avalanches: Small skier triggered windslab avalanche on Ruby at approx. 12,000 ft. on a 35+ degree, SSE slope. Slide broke near rocks during our initial bootpack approach and propagated approx. 25 ft. with an eventual path approx. 60 ft. wide and 90 ft. long. Fast moving bed interface, some slabs were 6-8″ thick. Skier was caught but not carried or buried.

Snowpack: Snow was variable, breaking trail it felt supportive until higher elevation, that’s when we got our warning
