Snowpit Observations
More detailed information about the snowpack: 

Toured up to the Lake Mary ridge today to measure the snowpack and perform stability tests on the persistant deep slab in the current snowpack.  The weather was clear with light winds out of the South accompanied with strong solar radiation.  A D1, R1, loose wet avalanche was observed by a member of the party on a E facing aspect near the dike wall. Our stability test was performed on a N/N/E, 30 degree slope at 9120'. The snowpack was measured at 175cm.  Ski Penetration 15cm, Boot Penetration 35cm, with CTH SC 88cm down, in 3cm thick 2mm faceted rounded particles.  The column failed at the first layer showing signs of faceting with several thick layers of more well developed facets existing below.  No more test were done due to time.
