Regions

Jasper, Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Maligne, Marmot, Miette Lake, Pyramid.

If new snow exceeds 20cm from Saturday to Sunday, expect avalanche activity and sensitivity to increase into the considerable range until it has had time to settle.

Confidence

Moderate

Avalanche Summary

Saturday's field team had very poor visibility and no avalanches were noted nor whoomphing or cracking. Friday at noon a size 1.5 occurred on the very bottom the steep rocky slab of Parkers slabs just south of Parkers summer trail. It did not travel very far. Nov 20th observed a few size 1 human triggered wind slab avalanches in steep alpine morainal terrain.

Snowpack Summary

Saturday to Sunday's forecasted 10-20cm of new snow will freshen up the top. Travel remains supportive in Parkers area yet overall, snowpack is highly variable across the region. Parkers manual weather station near Parkers ridge, is a protected treeline location, registers 96cm height of snow. A 2cm thick crust can be found up to an elevation of 2200m. Maligne has much less snow overall.

Weather Summary

The Icefield's weather forecast is for 13cm new snow, -4 °C, and light to moderate Southwest winds. Sunday will be cloudy, flurries, 4cm of snow, -4 °C, and light West winds. Monday to Wednesday are expected to be sun, cloud, flurries, -15 °C and light winds.

Terrain and Travel Advice

Small avalanches may cause climbers to fall or bury belayers and gear.
Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
