Snowpack Summary
Snowpack observations and information are limited, and conditions across the region vary. Early season forecasting relies heavily on the weather forecasts.In the alpine I suspect anywhere from 50-100 cm of snow. Storms slabs and wind slabs likely exist in alpine and treeline elevations. An early season (Nov 8) rain crust has been reported to exist around 2000 m and above on NW-NE aspects. I have no further information in regards to this crust, how deep its buried or reactive it may be.Snow depths at treeline are roughly sitting around 30-50 cm in depth, and below treeline snow levels may still be below threshold.
