Snowpack Summary

There is a 1-5cm breakable temperature crust on all aspects below 1700m. Also a sun crust on solar aspects to at least 2100m. The midpack is mostly solid but there could be a Feb 13 interface down 20-50cm as a suncrust on solar aspects and a facet layer on polar aspects.

Avalanche Summary

No new recent avalanches have been observed around Jasper

Confidence

Due to the number and quality of field observations

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.
