Overcast, Graupel squalls in the am, 20s, Moderate ridegtop winds out of NW easing in the afternoon

small pocket pulled out on southerly facing side of rocky point, looked less than a foot deep and about 50 feet wide no other avalanche activity noted

insignificant cracking in first few inches of snow right off the ridge

loading had occured on southerly aspects and terrain features, wind had either made hard slabs or scoured windward aspects and run out of snow to transport by late in afternoon

few inches (varied widely due to wind) of graupel on top of rime crust rime crust was very crumbly, thin and distibuted unevenly, not the great sliding surface we had expected

Snowpit results- CTM11 Q3 6" from surface underneath rime, CTM13 Q2 18 inches down (in layer where people have been noting facet formation

May have been considerable in am but we found no energy in the snowpack, more like moderate in our area Of interest was the weakness 18" down in snowpack, more sensitive and cleaner shear than results just a fewdays ago. Seems small grain factes haven't grown but the layer has increased in thickness
