Regions

Jasper.

Up to 35cm of new snow in some areas around Parkers Ridge. Great skiing to be had. There is a lot of snow available for transport if the winds pick up, heads up for developing wind slabs. Be aware of new slab formation as the storm snow settles.

Snowpack Summary

Parkers Ridge Area has received up to 35 cm of new snow in the past 4 days, this snow was accompanied by light winds and warm temps. A crust below the top 25-40cm of snow is decomposing and can be found below 2500m on south aspects. There is a weak facet snow layer at the bottom of the snowpack, this is widespread throughout the park.

Avalanche Summary

Jasper Visitor Safety preformed avalanche control on Thursday in the Parkers Ridge zone. Explosives control produced a few slab avalanches up to size 2 on east aspects. No new natural avalanches observed.

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.
