South Columbia

Be cautious of wind slabs on all aspects near ridgelines. Remember recent wind directions have varied.

Sheltered terrain features will hold the best riding conditions.

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

On Saturday explosive control produced several wind slab avalanches size 1-1.5 on south facing slopes.

Light snowfall continues to fall over wind affected snow in exposed areas, and up to 30 cm of settling snow in sheltered terrain.

A weak layer consisting of a crust, facets, or surface hoar is buried 30- 70 cm deep. Observations are limited this early in the season. While the extent and reactivity are not fully understood, we have not had recent reports of avalanches or test results on this layer.

Treeline snowpack depth is around 120 to 160 cm.
