Avalanche Summary

On Friday, several wet loose avalanches, up to size 1, were observed on alpine features that received direct sun in the afternoon.

Several large (size 2) natural slab avalanches were reported near Fernie on Thursday. The group observed the avalanche's release when the sun hit open alpine slopes.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

The top layer of the snowpack at higher elevations is made up of 20 to 40 cm of dense, wind-affected snow. It tapers to a rain crust below 1400 m. This Top layer of snow may sit on a sun crust on solar slopes and small surface hoar in sheltered, shaded areas. A sun crust is found on the surface of solar slopes at all elevations.

The mid-snowpack is generally well-settled. The lower snowpack includes a layer of weak sugary crystals near the ground. This layer has not produced recent avalanche activity.
