Snowpit Observations
More detailed information about the snowpack: 

Today we rode up around Leavitt Lake in the BWRA. Skies were broken and temperatures were relatively warm. There were moderate to strong winds generally out of the SW but they seemed somewhat erratic, gusting out of other directions as well. There was some snow blowing around in the alpine, but it didn't seem to be effectively loading anywhere. We observed no signs of instability today and no recent avalanches. 

On a NE aspect around 10,300 ft we measured the snow depth along a transect across the slope. The snow depth was very variable, ranging from 50 cm to over 250 cm over a short distance. We targeted a shallow area with a depth around 75 cm to dig a pit that was representative of a potential trigger point for a deep persistent slab avalanche. We found around 25cm of 4F hard facets under a 50 cm thick slab (see pit profile). The facets were unreactive, producing no results in ECT's and resulting in a PST 86/100 (END). We observed non propagating fractures on density changes within the slab. We also observed a thin rain/rime crust at the snow surface.
