Avalanche Summary

On Monday there was one size 1.5 natural wind slab avalanche from a steep headwall near Fernie.

Snowpack Summary

A small amount of new snow sits over variable layers including crusts on solar aspects, old faceting wind slabs, and well-settled powder.

The upper snowpack contains a couple of thick, hard crusts buried 10 to 20 cm and 30 to 70 cm deep. Below, the midpack is well settled.

The average snow depth at treeline varies widely from 50 to 130 cm, with the deepest snowpack around the Fernie area. Snow depth tapers rapidly at lower elevations.
