Low

Avalanche Summary

No new avalanches have been observed or reported in the bulletin region in the last few days.

Snowpack Summary

The snow pack is highly variable across the region with the deepest zone being around the Icefields, which has about 60 to 80 centimeters at tree line. Since the end of the storm on Friday, moderate SW winds have continued to transport snow in open areas. There is not yet much information available about the early season snowpack structure, so be sure to dig down and investigate if you're heading out, and post your observations to the MIN!

Terrain and Travel Advice

  • Small avalanches may cause climbers to fall or bury belayers and gear.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.

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.
