    Found mainly on open lee slopes and cross-loaded gullies. At lower elevations use caution on classic trouble spots like moraine features and larger open slopes with convexities.

  • Loose Dry

    Cold temps promoting facetting of upper snow pack. Expect loose dry avalanches from steep terrain.

Weather Forecast

Cold temps continuing but, the inversion is helping inspire you to get up high where it's more bearable (-15 to -20).

Snowpack Summary

Shallow snowpack areas facetting out to ground and losing cohesion quickly. The upper snowpack is a mixed bag of surface hoar, surface facetting, or layered rotting windslab above the Nov 12 crust (down 45-90cm). The crust is maintaining support for travel above 2100ms. Below 2100ms expect to be walking on the ground.

Avalanche Summary

Road patrols on the Maligne Road and Icefields Parkway observed 3 significant slab releases up to size 2. These were likely triggered from a combination of weak solar input, triggering a point release from the exposed rocks and hitting the shallow slope below. Several of these point releases in similar features noted on steep S aspects.
