More detailed information about the snowpack: 

Today we snomobiled up to the Leavitt Lake area with our Avalanche Awareness Class. There were some clouds over the high peaks in the morning that cleared thoughtout the morning leading to mostly clear skies by the afternoon. Winds were lighter than expected today with only some light to moderate winds in exposed areas around Leavitt Lake. Temperatures were warm. 

Last night's extreme winds did some damage to the snowpack. We observed signifcant wind scouring, even in some more protected areas. Many old tracks are now raised above the snow surface. We did not observe any fresh snow, but there were some new wind drifts. It seemed like the wind mostly caused the transported snow to sublimate, but new wind deposits were present in isolated areas well below ridge tops. We only observed minor cracking in the new drifts on small test slopes. 

Solar heating was significant today. The top several inches of snow on southerly aspects near and below tree line became wet. Wet loose avalanches may have been possible in steep terrain. We didn't travel above tree line to see if the winds were keeping things cool up there.
