More detailed information about the snowpack: 

Lots of blowing snow throughout the day in the Mammoth Area. Consistent saltation below the main ridge and on the E side of sub-ridges on the Sherwins. Consistent moderate W winds. (See video) Snowpack tests down low on Panorama dome and lower Mammoth Rock bowl were inconclusive. Up higher under the top of the Hose was a slightly different story.

1600- N aspect, 35 degree slope, at 9500', large opening in the trees on the leeward side of the ridge separating Mammoth Bowl from the Hose area: CTE SP down 45cm x2, ECTP24 down 45cm x2. Top of the snowpack was a strata of wind deposits and facets: 1cm of 1F wind skin over 10cm of 4F wind deposited rounds over 15cm of 4F- facets over 20cm of 1F wind deposited rounds (about 0.5mm) over 3cm of 1.0mm F hard facets. Test results were failing on the interface between the 1F wind slab and the F facets.
