Recreational Observation

Toured from Hyak to twin lakes, then onto cold creek trail and ascended steep trees a few hundred feet east of actual summer trail, the trail that leads to a saddle (pct junction/mirror lake junction). My partner and I crested the ridge to the NE of the junction, bypassing the saddle. At the ridge we experienced sustained 20mph winds from the SW, loading the slopes 100+' down from the ridge. We traveled only 40' across the ridge before i triggered a small isolated pocket of wind slab, about 10'' deep 20'x20'. larger slabs surely lurked nearby. Our intent was to travel this ridge in its NE direction to a prominent terrain feature to ski straight down to twin lake. The steep trees on the way up were very stable so we reversed the route back down to cold creek. Mucho fun. More loading throughout the day surely built these near-ridge slabs up even more.

Weather: Snowing heavy. Sustained 20mph winds from SW.

Area Description: NNW facing slope above twin lakes/ cold creek 4800'

Avalanches: Triggered islolated pocket of wind slab, 10'' deep, 20'x20', NNW aspect, 12 feet below ridge crest. Very sensitive, triggered easily. Trees and benchy terrain stopped it from running from far. Count on these slabs being much larger today...
