Snow surface

A very thin, breakable rain crust over a few inches of new snow, 4F to 1F wind slab, or sastrugi.


Snowpack varied considerably from a foot deep on the flat slopes on the way from the parking lot to Blueberry Hill, to stripped to ground on the top of Blueberry Hill, to between 60 cm to up to 280 cm deep in wind loaded leeward Northerly aspects on Blueberry Hill. We dug several pits on N to NW aspects on Blueberry Hill. Aside from a thin layer of facets 6" down, the snowpack was 4F decreasing to P hard wind slab on top of a thin layer of basal ice at the ground. We did not get very reactive results in our snow pits on this layer. Many ECTXs, ECTN in the 20s, CTNs, and CT teens to 20s SP, RP, & PC.
