More detailed information about the snowpack: 

Went out to get above treeline on ridgelines to see what the storm slab was doing was doing.  Lot's of low density snow made for easy conditions to break trail, even in the deep snow.  Winds were calm and snow was only transporting at ridgelines above treeline.  Soft storm slabs had formed just below ridgelines, but these slabs were mostly only extending 100' below.  Ski cuts were effective with storm slabs breaking 1 to 2' in thickness, but not running very far.  This was one of those rare storms for us that ended cold with very light winds.  Most steep slopes on all aspects were sluffing loose dry snow.  We still find shallow snowpacks above treeline with weak faceted layers that we are still able to get to fail with moderate to hard force.

Photo 4: Lots of low density snow

Photo 5: Persistent weak layers that we continue to get fail with moderate to hard force

Photo 6: Slab that we were easily able to trigger just below the ridgeline on a N aspect
