Quick report
APU snow science class toured up Cornbiscuit seeking dry snow on northerly aspects. The weather was overcast and just below freezing when we started the tour at 10am. Visibility deteriorated throughout the day with a dropping cloud ceiling. Light snow began around noon, and when back at the vehicle at 2:30pm the temperature was 37F and it rained. Not much wind all day, some moderate gusts at the ridgeline. Surface conditions were variable throughout the day. We skinned on cold melt freeze crust (~3cm) at lower elevations. The southerlies had 5-8cm sun crust from mid to high elevations. The snow stayed dry on the way up. On the way down, the surface snow was moist 2200' to 1800' and got stickier below 1800'. Rain line was at 1200'. We skied one of the northerly couloirs and knocked off a very small wind loaded soft slab at the rollover when entering the run. It was shallow, ~20cm deep, and it did not run far or entrain much snow. In the couloir we had significant dry loose sluffing, enough to knock me off my feet. Only other avalanche we observed was a small natural wet loose from previous day(?) on SW aspect off the skin track at ~2800'. The visibility and flat light were not very good for looking for avalanches.
