More detailed information about the snowpack: 

Yesterday, North of Tamarack, Dave and I had shooting cracks in the upper 40 cm of the snow while starting to dig a pit at abot 5900 ft, ENE Tamarack Falls-West Mountain North of Tamarack Resort. In the pit, we found a very weak layer of surface hoar 40 cm down that failed in compression as soon as he put his shovel on it, and it failed in an ECT as soon as we cut/isolated it.We also noticed a fresh crop of surface hoar forming on the snow surface of a West aspect near ridgetop.
