Signs of Unstable Snow

Observations

Toured up along the west end of Mushroom ridge today near the gnarnia chutes. Didn’t see any evidence of wind effect until I was heading out around 3:00 - southerly winds were blowing snow at a moderate rate at the ridgeline. Dug around on a couple different aspects to see how the new snow was behaving. Didn’t see any reactivity at the new interface, but I did get an ECT to go on a SW aspect (9400 ft, 1:00 PM, ECTP11) about 40 cm down from the surface. There was a small layer of near surface facets (about 2 cm thick) underneath a series of pretty solid crusts. Didn’t observe reactivity or presence of this layer on every aspect, so don’t know if it’s widespread or not. Overall, didn’t observe significant instability in the new snow, and I skied terrain over 35 degrees on N aspects where it was still cold and dry.
