Weather

Clear and mostly calm winds during the day. Slightly breazy from a NW wind on the ridge near the top.

Snowpack

The snow pack is very variable in depth ranging from 0-100 cm on solar aspects, with a bit more on the shaded aspects. Hard wind slabs were predominate above TL and were universally distributed throughout the terrain. The slabs continue to sit on very weak depth hoar. One snow pit revealed a CTVE on a SSE aspect at 11,920 with ~40 cm Knife hardness layer on top of 4F facets. Another snowpit revealed two CTM(11) SC on a NNE aspect at 11,187 with ~60 cm P hardness on top of F facets below. Some cracking was observed BTL on a steep E rollover, but no movement was observed.
