Snowpit Observations
More detailed information about the snowpack: 

Huckleberry hadn't been open in a few days, and remained closed today (observations done with Sierra Patrol). Although technically "inbounds," snowpack was more representative of bc terrain than inbounds.

 

Several test pits showed easy to moderate shovel tilt and CT fractures at the interface between yesterday's windslab and last night's storm snow, at ~20cm. Weak layer was storm PPs with some graupel included. Minimal graupel (not expected to be persistent), but may help with future ID.

 

All videos: 33 degree incline, 335 degree aspect at given lat / long coordinates.

 

Video 1: RB2 WB at yesterday's wind slab/ last night's storm snow interface.

 

Video 2: ECTP 11 Q2 at same interface.

 

Video 3: PST 40/100 End.

 

Several test slopes were ski-cut, with results limited to undercut slopes.
