Snowpit Observations
More detailed information about the snowpack: 

We did a ​compression test at about 9000 ft. (elevation correction) on a north facing slope.  Total snow depth was 185 cm with 115cm of new snow.  The new snow pack was right side up.  There was a noticeable change in density at 40cm down from fist to one finger.  The remaining 75cm of new snow is well consolidated storm slab, one finger.

we found a resistant failure at 40cm. CTH 30.  shovel sheer removed the remaining 75cm of new snow in one big consolidated block.

The total snowpack is very upside down.  Below the new storm total, we found very loose, sugary, and faceted snow to the ground.  Last week's surface hoar and persistent facets still present. 

We observed previous and ongoing snow settlement throughout the day.  Visual and audible whoomphing, snow falling from trees, diminishing snow heighth.
