Snowpit Observations
More detailed information about the snowpack: 

Snow depth around Smuggler's between the Red's Lake area and Minaret Vista are between 65 and 75cm. Snow surfaces range from old, faceting, Pencil hard wind slab, to 2 to 10cm deep large unconsolidated surface facets anywhere things are sheltered, to melt-freeze crusts anywhere things are exposed to the sun. Several hand pits pulled out with hard force in a layer of large sugar grains underneath of a firm, but faceting crust. Several test slopes had no results beyond some sloughing in the surface facets. Compression tests at 9400' on a WNW aspect where inconclusive: CT15 BRK X2 down 15cm in the same facet layer observed in hand shear tests. Upper snowpack structure: 0-2cm F hard facets; 2-7cm P hard old, faceting wind crust; 7-20cm 4F hard facets; 20-21cm MF crust; hard rounds below that. Some places had a softer layer (I assume basal facets) near the ground but that's just based on probing since nothing I was seeing really prompted me to dig a full profile. Air temp was warm and well above freezing, but the snow is cold. Especially in the trees or on shady aspects. Sunny aspects were bare ground.
