Avalanche: Summit

Location: Tenderfoot

Route & General Observations

Went to try dye tests in 2 locations. Several new glide avalanches observed. Numerous WL, some stripping snow to ground. A few Wet Slabs on S & East aspects. Only Westerly WS observed was on Moose mtn approx. 1100′ elev.
44*F @ road. Calm skinned SW-W facing slope. 1″ wet snow above 1.5″ semi-supportable crust & iso to the ground. 1800′ skif over 2-2.25″ supportable crust w moist snow below & some horizons of wet snow. Could easily push pole to ground at these elevations. By 2800′ very firm, dry and cold surface on ridge.
