Snowpit Observations
More detailed information about the snowpack: 

Went to Chicken Wing to check out distribution and reactivity of buried facet layer.

No cracking, whumping or avalanche activty noted during this tour. 

9:30 Parking area at 8200 ft. Cloudy. Air temp=3.5C. Light breeze from the south.

10:45 Dug a pit at 8600 ft on a 26 degree slope, N facing. Total snow depth of 135cm. Fist and 4 finger density snow from 135 cm (surface) to 35 cm.  Crust present at 35 cm with facets below this to the ground.  I performed a deep tap test 15cm above this crust layer.  DT17 with sudden planar collapse on facets a few cm above the ground. 

A hasty pit dug at 9000ft on a north facing slope revealed a similar snow profile. Probing N and NE facing slopes during the tour showed the faceted layer to be widespread. 

12:00 Dug a pit on due east facing aspect below summit of Chicken Wing. Air temp=4C. Total snow depth=55cm. Snow surface was a thin melt freeze crust (still frozen today) on top of fist and 4 finger snow.  No facets noted, I'm guessing this was bare ground before the last storm. CT27 with sudden planar collapse on a slight density change near the ground. 

We found good skiing on N and NE aspects, with occasional thin melt freeze crust. Melting noted in the flats on the way back to the parking lot, even though the sun was obscured by clouds most of the day.
