Avalanche Summary
No new avalanches were reported in this region on Thursday. This may speak to a lack of observations rather than actual conditions. Please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
Up to 40cm of new snow has fallen in the past few days. At higher elevations, southerly winds (gusting strong at times) likely redistributed the new snow, forming wind slabs on lee features.Below the recent storm snow you may find a couple of crusts which formed as a result of last week's rain. That said, little is known about the reactivity of these crusts or the elevation bands at which you're likely to find them. A major feature in the snowpack is a crust which formed around November 11th and can be found approximately 120cm down at treeline elevations. The depth of the snowpack varies greatly with elevation. Recent reports suggest the average depth is 200+cm in the alpine, 100-180cm at treeline, and decreasing rapidly below treeline where the primary hazards are rocks, stumps, and open creeks. We currently have very limited snowpack observations within this region and it is critical to supplement this information with your own observations.
