Snowpit Observations
More detailed information about the snowpack: 

-Toured up V-Bowl to top of dana plateau (11,700'), back down to Rd closer to power house area.  

-Wind effected snow throughout tour from 8000' to 11,700'.  Lots of firm wind-board which was formed during this past Monday's storm/wind event.  No signs anywhere that we encountered of sensitive windslab.  

-2:15pm,  9800', SE facing 15 deg slope:  Top 7-8cm of snow was moist, below was dry.  

-Evidence of small wet point releases likely from yesterday or day before coming down from near rock bands on E to SE facing steep slopes above 10,000'.

-Most concerning safety factor today was very firm snow conditions on steep upper elevation slopes.  Slide-for-life conditions for sure.  

-Lots of smooth firm surfaces could make for good sliding surface for upcoming snowfall to slide on.
