More detailed information about the snowpack: 

My partners and I toured up over Lake Fork and down the backside to assess the snowpack in the Rescue Creek area of the S. Fork drainage.  The Williams Lake drainage held a melt freeze dominated snowpack in the morning, making for easy travel but less than ideal skiing conditions.  Once over the ridge on the S. Fork side, we found dry snow and near surface facets on the North faces, and sloppy, post corn snow on the South faces after 1:30pm (see video).  Our avalanche concerns focused on the rapid warming of the solar faces and the wet loose slide potential.  The south facing snowpack was wet to the ground (see pic) with snowpack temps ranging from -.5degreesC to -1.5degreesC.  That said, we were not able to get the surface snow moving at midday, but noted we would not have wanted to be on steep sunny slopes later in the afternoon, as the warming trend was very noticable.
