Regions

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

Up to 40cm of new snow fell over the weekend, which has improved the ski quality. Look out for new wind slabs above treeline. Dry loose avalanches may still occur in steep terrain until the recent snow has a chance to settle.

Confidence

Moderate

Avalanche Summary

Sunday's Icefield team noted numerous loose dry avalanches up to size 1.5. Some were triggered in that afternoon as the sun came out. There was one slab avalanche observed. A size two in the fan of a couloir on Snowdome.

Snowpack Summary

The Icefields received up to 40cm of new snow this weekend. Moderate southwesterly winds have created new windslabs above treeline. The mid pack generally consists of firm windpressed snow from earlier wind events. Snow amounts in the alpine vary greatly, with some areas blown free of snow, while other areas are filled in. The weather station near the Parkers parking area has a snow depth of 110cm.

Terrain and Travel Advice

Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Expect slab conditions to change drastically as you move into wind-exposed terrain.

Problems

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.

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.
