Snowpack Summary
Snowpack observations and information are very limited, and conditions across the region vary. In the alpine I suspect anywhere from 150-200 cm of snow. Storms slabs may be widespread in the alpine and treeline elevations and wind slabs are likely found on lee slopes and behind ridge crests. An couple early season persistent layers have been reported. The most reactive being a surface hoar layer that was buried on November 17th. This is down 25-50 cm and producing easy shears in snowpack testing. The early November crust also exists deeper in the snowpack and widespread in the alpine. At this point it seems to be unreactive in the Dogtooth Range, but may catch you by surprise in other parts of the region. Snow depths at treeline are roughly sitting around 50-100 cm in depth, and below treeline snow levels may still be below threshold.
