Avalanche Summary

No new avalanches were reported on Monday, however, there is currently very limited data for this region. Please report your observations to the Mountain Information Network(MIN).

Snowpack Summary

Observations are very 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.
