No avalanches were reported in this region on Tuesday. However, we currently have very few observations from within this region. Please post your observations to the Mountain Information Network (MIN). Although not in this region, a notable size 3, human triggered avalanche was reported in the South Columbia region on November 24th. The avalanche reportedly occurred on a northwest aspect, on a lee feature in the alpine and likely ran on a crust near the bottom of the snowpack.

Ongoing snowfall since Sunday night brings total recent storm snow amounts to 40-90 cm. This new snow sits on top of a weak layer of surface hoar (feathery crystals) and sun crust on steep south facing slopes. The surface hoar is most pronounced at treeline and below, but it may be found in sheltered alpine areas.At the base of the snowpack is a crust that formed in late October. There have been no reports of reactivity on this layer in the North Columbia region, however with recent snow, winds and high freezing levels, this layer could become active in isolated locations. Total snowpack depths vary greatly with elevation. Recent reports show depths of 120-210cm in the alpine, 80-150 cm at treeline and 10-120 cm below treeline.
