Snowpack

Observed a lot of spatial variability along the Crater Lake Trail up to the ramp area south of Andrews Lake. Pit analysis within this area on a NNE aspect at 10,945 ft BTL showed persisting large facets to the ground under built up slabs where wind loading was present. These slab layers demonstrated the strong ability to step down onto each other when a fracture occurred.
