Great sunny weather to be getting up high and enjoying the expansive views. Good skiing can be found in sheltered treeline features
Weather Forecast
A cold morning -31 will see day times highs around -13 down south. Expect mostly light winds and clear skiesWednesday: Will see broken skies and -9 as a day time high with moderate gusting N winds in the afternoon Mountain weather forecast available at Avalanche Canada.
Snowpack Summary
Towards the Icefields, the alpine is wind affected. The Jan 18 surface hoar layer (down 40cm) has faceted away in most places, but shows isolated sensitivity at treeline and below in the Ice fields region. The midpack is mainly supportive, over depth hoar in shallow areas. Although structurally weak, this layer has been generally dormant lately.
Avalanche Summary
No avalanches were observed in the Eastern part of the park today. The snow pack continues to facet with cold temperatures.

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.
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
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.
