Observations
We skied the furthest looker’s right of the Kendall Slidepaths, where there was a thinner wind skin rather than a wind slab. Field Obs collected between 12:00-1600.
Avalanche Obs: No new avalanches observed.
Snowpack Obs:
Below 4100’: Btwn 20-30cms of highly faceted new snow (F-) sits above the Feb. 19th MFcr.
Above 4100’: Wind affected snow exists in all but the most sheltered features. Range of wind affect spans the depth of 10-25cms, and is shallowest on SW aspects, and deepest on NW-NE aspects. Wind slab on SW aspects was non-reactive in ski cuts.
Weather Obs: Cold & clear. Light E winds.

Advanced Observations
Observed Avalanche Problem #1:
Wind SlabComments:
Widespread on all aspects above 4100,’ but increases in depth with elevation.Likelihood of triggering: possible-likely
Size: D1-D2
Depth: Ranges from 10-25cms depending on elevation (higher being worse) and aspect SW having least depth of wind loading at approx. 15cms.
