Be on the lookout for lingering wind slabs in the alpine. Avoid likely trigger spots such as shallow, rocky, wind affected areas. Please post your observations to the MIN.

Avalanche Summary
No new avalanches were reported on Tuesday, however, there is currently limited data for this region. Please report your observations to the Mountain Information Network(MIN).
Snowpack Summary
Observations are limited in this region. Expect to find wind slabs in wind affected alpine terrain, especially below ridge tops. The crust formed in mid-November is down 60-80 cm. Average snowpack depths at treeline are 70-150 cm with generally less snow in the southern portions of the region. Early season hazards such as stumps, rocks, and open creeks remain the primary hazards below treeline.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
