Observation Date: 02/21/2021
Skied various E facing bowls from south to north on the day.
Temps hovering around 20ish on the day with snow flurries, wind chill felt near zero.
Sustained 20mph+ on ridges and peaks from the west, transporting snow to leeward slopes below ridgeline throughout the day.
New Snow: 6-12″
Pit results gave us ECTN12 at 25cm down of recent snow/soft slab on E face at 8040′, and ETCX at 120cm. Bottom of snowpack was faceted and over 1.5m down in the shallowest locations in which we dug/probed. New snow from last several days was well bonded to last week’s large storm cycle.
The slide we triggered occurred on a steep and short (~100 vertical feet, 40*) rollover on the E face off of the ridge north of Morrell Mt summit. Skiers were aware of the rollover and skied it one at a time. The third skier remotely triggered a soft-slab above and to the left of skier. Attached are photos of the outlined crown, which was approximately 20ft across and 15-20cm tall. Skier was not caught or thrown off balance. The slide runout was short, maybe 30 vertical feet below crown.
Cornices were very, very large and overhung on most ridgelines. We kept a wide berth and avoided traveling under them,
