    The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Confidence

Moderate

Avalanche Summary

Large avalanches have been observed in the west side of Jasper. No new avalanches were observed by the field team in Maligne on Friday.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
