Shaded slopes sheltered from the wind likely offer the best riding.

Numerous solar-triggered loose avalanches were observed from steep sun-exposed slopes on Sunday and Monday.

On Sunday, riders on a south slope in the alpine triggered a size 1.5 wind slab avalanche.

The snow surface is highly variable and consists of a melt-freeze crust on sun-exposed slopes, surface hoar and/or facets on shaded slopes, and wind-affected surfaces in exposed terrain at higher elevations.

A layer of facets and/or surface hoar buried in early December may be found down 50-100 cm, or as shallow as 30 cm around Invermere. This layer has generally gained strength and is currently not a significant problem.

The base of the snowpack consists of a thick crust and facets or depth hoar in many areas.

• The snowpack is generally stable; it may be appropriate to step out into more complex terrain.
• Make observations and continually assess conditions as you travel.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
