Evidence of Natural Windslabs on the Crest and Snowpack Observation
Signs of Unstable Snow
We toured into the Lakes Basin to get a look at mid and upper elevation terrain today and conduct a snow profile observation. Here is what we found supported by photos.
Evidence of windslab up to D2 that ran naturally during the loading event yesterday.
Wind was actively transporting snow at the sherwin ridge in the morning as we toured by.
Wind texture was present in exposed areas
Informal kick tests produced isolated cracking in the upper 30-40cm of the snowpack
Snow profile and column tests indicated it is possible to initiate a fracture in a week layer buried 30-40cm down, but that propagation was less likely due to weak overlying slab. This was in sheltered terrain only. Avalanche observations would indicate a strong enough slab where wind transport was evident.
