More detailed information about the snowpack: 

Very icy conditions at Carson Pass today. We abandoned plans to ski Red Lake Peak to Hope Valley, unable to find enough continuous edgeable windblown snow for safe descending. Another party reported that ice was consistent all the way to Little Round Top.

Snowpit: No signs of instability in this profile, nor via other obs in this area. New surface crust is quite strong, though may be worth monitoring in the future - both for new snow bonding and potential for PWL formation.

Pic 1: Thin saw required for cutting through surface crust, and still required effort. Note the trace of new snow and graupel on the surface and being blown by winds.

Pic 2: Windblown snow/graupel accumulating on stationary objects but being scoured from surface crust where there was nothing to anchor it, resulting in patchy accumulation patterns.
