Snowpit Observations
More detailed information about the snowpack: 

HS on this normally shallow side of Luther Pass was observed to be ~250cm. 

Pic 1: A small, shallow, natural triggered storm slab. Ski cuts immediately adjacent to this, and on a similar feature nearby, did not produce further propagation.

Pic 2: Kicking test slopes showed obvious loose instabilities but snow was too un-cohesive to propagate. 

Pic 3: Several profiles in this area indicated a storm instability 50-70cm from the surface, but all ECTs required additional loading steps after initial fracture to propagate across the column. CTs were Resistant Planar at this same height.
