More detailed information about the snowpack: 

Snowline starts just above the Buttermilk Bouldering area, but with a high clearence vehicle we could get another 2 miles or so up the road today before parking. Snow through the sage and lower elevations was supportable and made for good travel. Snow on the base of Basin Mountain was shallow and solar aspects were crusted up. Roller  balls were present on most of the East aspects. All of the main gullies on Basin had slid at some point during last weeks storm and debris had reached the lower flanks of the mountain. Flat light and blowing snow made it difficult to see any crowns. 

We decided to make treeline and scope a northerly aspect. The top 15cm was soft windblown powder and made for good skiing in the whitebark pine and lower sheltered gullies where winds had transported snow. Compression and Extended Column  tests  showed overall good stability, but fairly well developed facets do inhabit the bottom 50cm of the snowpack. Did not experience any collapsing or shooting cracks.

More detailed information about the weather: 

The wind started picking up around 1030am and the High peaks were becoming more obscured with flurries in the air at 1230am. Snow was visible swirling and blowing from all directions near treeline early this afternoon. The Owens valley was in sun while the Sierra became increasingly enveloped with cloud cover through the day and temperatures were just below freezing above 10000ft. It was -2c at 100pm.
