Snowpit Observations
More detailed information about the snowpack: 

A brief tour up through the storm into Mammoth Rock Bowl with the boys from San Diego.  It was breezy with strong gusts as we got into thinner patches of trees.  Wind transport was obvious with some areas being scoured down to old snow and others drifting in.  Snow depth is highly variable in the area from 0 cm to over 200cm HS.  The new snow from overnight(HST) was approximately 2cm with drifts as deep as 10cm in sheltered areas.  We did not see any shooting cracks in the newly deposited snow even where it had been pushed around and stiffened by wind.  At the upper end of our tour the new snow was pleasant to ski where we could find smooth panels of underlying snow.  There were plenty of tracks around and those were less fun to cross.
