More detailed information about the snowpack: 

A superficial refreeze above 11,000' last night.  First night without a good refreeze last night.  Temperatures warmed quickly throughout the day. Daytime winds remained calm to light out of the west which didn't keep the surface cool even above treeline on solar aspects.  We saw more roller balls and pinwheeling today on east and south aspects while we were out there.  I think were heading to a potential wet slab problem assuming we don't get a good refreeze tonight.  Boot penetration was too the ground in many spots below and near treeline.  There are lots of melt-freeze/ sun crusts in our snowpack that could be a concern if water percolates down to these layers.

Photo 1: An idea of ski vs boot penetration in spots.

Photo 2: Wet facets on the ground.  You can make a snowball with them!

Photo 3: A roller ball that didn't go very far.
