Snowpit Observations
More detailed information about the snowpack: 

Skiied into the Sherwins today to check stability of recent new snow (and to have some fun).

Began touring around 1pm from standard approach parking lot. Moderate wind gusts from the West with some snow transport noted at the start of tour, with decreasing strength during the day.  No cracking or whumping noted during this tour.

Ski pen generally 15-25cm, depending on elevation. Some melting occurred on solar aspects, north facing aspects did not melt today. 

During the skin up we dug several hand pits on north and northeast facing slopes between 8600-9200 ft. These failed with easy to moderate force on the interface between new snow and older melt freeze layer. Kick tests on small, wind loaded rollovers produced only small, localized cracks that did not propagate. 

At 9200 feet we dug a pit on a north facing slope. Total snow depth was 145cm. CT22 with progressive collapse 40cm below the surface on slight density change.
