Recreational Observation

Toured roughly SSW up ridge just E of Silver Star Creek, then took NE/SW running spur of ridge to access Silver Star Glacier. Skinned up glacier to ~300 vertical feet below saddle at top, N of peak, then skied down and out Silver Star Creek.

Feb. 25, 2017, 2 p.m. PST

Weather: Sunny and breezy from highway, then windy with gusts ~30mph from WNW on ridge, then from W or WSW on glacier.

Snowpack: Wind-affected snow prominent on lee (S) side of ridge and on glacier proper. Mostly ~2" thick wind 'skin' with slab characteristics over looser snow, with some deeper wind loading/slab evident in areas on ridge. On glacier, mostly firm wind-affected snow. Crust (likely from 2/14) underlies snow ~12" deep in most places; snow mostly seemed well-bonded to crust.

Area Description: Silver Star Glacier and adjoining ridge running roughly SW/NE from E flank of Silver Star Creek.

Avalanches: One small ~50ft long point release buried me to shin level ~300' below saddle on Silver Star Glacier. Point of origin was steeper rocky section in middle to looker's right below saddle. Suspected trigger was small cornice fall or other source of impact perhaps mitigated by wind, but visibility was too poor to verify. Consistency of slide snow was slab-like, firm wind-affected but slide itself clearly wasn't a slab release. No further propagation occurred and snow on glacier otherwise seemed fairly stable.
