Time: 1030-3pm
Route: Down Nosebleed then up to the Gold Chord hut, back down via SE aspect and cross hill
Weather: Few clouds, temps in 20s.
occasional light south to east winds, but some periods with moderate snow transport observed on ridgeline in the afternoon.
Snowpack: variety of surface conditions but generally ski penetration of 1-6ā of soft snow depending on aspect. occasional thin wind slabs – up to 8ā thick – on more northerly or westerly aspects. No formal tests, but a majority of these slabs sat on a softer but relatively thick layer, and w/ moderate results on hasty hand shear tests. Mid-elevation cornices in test slopes were quite soft and would fail with skier weight, but just under foot.

Observed one d1 slab, ~2-6ā thick, get triggered directly by a snowboarder off the top of nosebleed, and several other d1 slides on north to west aspects of nosebleed/microdot triggered throughout the day. From seeing other wind deposits iām also thinking soft slab in nature. See pictures below.
