Snowpack Discussion

Surface conditions vary from wind affected surfaces in exposed terrain at higher elevations, and settling snow in sheltered areas that may include a layer of surface hoar buried 5 to 10 cm deep. Warmer temperatures will likely affect the surface snow and produce a crust overnight.

The mid snowpack is generally well settled, with an early November crust buried 50 to 100 cm deep. This layer is understood to be more notable in the Selkirk Mountains.

Snow depths at treeline are roughly 80 to 150 cm, and decrease rapidly at lower elevations.

Avalanche Activity

One large slab avalanche (size 2.5) was seen from a steep south aspect. Reports suggest it was several days old.

Wind slabs continue to linger in the region, with reports indicating they are stubborn to rider triggering.

Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network.
