Avalanche Summary
On Wednesday, only sluffs and small dry loose avalanches were reported.
Observations in this region are limited. If you head into the backcountry, submit a MIN report to let us know what you see.
Snowpack Summary
Expect to find wind slabs on leeward slopes in the alpine and at treeline. Recent snowfall varies across the region. 20-40 cm of settling snow sits on small surface hoar or a thin crust in specific terrain.
A crust buried in early December is 50 to 85 cm deep. In some places there are weak facets above the crust, but it is not a current avalanche problem.
The mid and lower snowpack are generally strong and well settled.
The snowpack is 100-150 cm deep at treeline.
