Turn the bulletproof hard slab above treeline from an enemy to an ally by using it for quick travel on long flat alpine tours.Good time to go ice climbing!
Weather Forecast
Light scattered snowfalls through Thursday. Return to more seasonal temperatures (cooling trend). Winds moderate to strong at ridgetop.
Snowpack Summary
Any small amounts of new snow that fell in the last 48hrs was hard to find in both the Parker Ridge area and the Maligne valley. Recent strong winds have obliterated most loose snow on most aspects above treeline and left a widespread persistent hard slab on the surface, covering 50-70cm of facets. Below treeline the midpack is weak.
Avalanche Summary
No new avalanches in Jasper or signs of instability related to the widespread persistent hard slab above treeline.
Confidence
Intensity of incoming weather systems is uncertain
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.
