- <p>Loose Dry still main activity observed. Loose Wet activity has subsided, but would still be leery of pockets around steep rock bands. Some slopes just off the highest ridgelines may have small wind slabs that would be sensitive to ski cuts. </p>
Photo 1: skier triggered Loose Dry on Miller Hill Northeast Photo 2: Surface hoar growth in low meadows (2 to 3 mm) Photo 3: Wet activity on low elevation Northeast faces of upper AF canyon Photo 4: Rain crusts from 2/10 down 35cm and early Feb down 70cm. Total HS is 340 at 9500' in sheltered areas of upper AF. CTH BRK down 25cm on graupel above crust.
Snowpack
- Instability Comment
- <p>Weaking of the snow surface continues. These cohesion-less sluffs get going with minimal provocation and run quite a ways, either on a semi frozen rain crust or within density changes in the new snow depending on elevation. This is likely going to get worse before it gets better. </p> <p>Still very warm in the sun, and there are wet loose avalanches on every slope steeper than 35 degrees that receives any solar input. Predictable timeframes of late morning through early afternoon depending on aspect. </p>
Continued faceting in top 10cms of snowpack. Surface hoar growing in sheltered meadows where trapped humid air remains or where there is a vapor source like a creek. Damp powder exists at highest elevations on solar aspects, but mostly a combo of crusts with radiation recrystalization taking place. Wind crusts are breaking down with diurnal temperature fluctuations.
