Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Low danger does not mean no avalanches.

Continue to use good travel habits; only expose one person at a time and avoid unnecessary overhead hazards.

Confidence

High

Terrain and Travel Advice

  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • Avoid travelling on slopes below cornices.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
