Regions: Kootenay Boundary.

Avalanche conditions are generally safe. As always, use caution around cornices and practice safe travel habits.

Confidence

High - The snowpack structure is generally well understood.

Avalanche Summary

We did not receive any reports of avalanches on Saturday or Sunday.

Please consider posting your observations to the Mountain Information Network to supplement our data stream and help fellow recreationists.

Snowpack Summary

A dusting of snow overlies a hard melt-freeze crust in most areas. Small pockets of old wind slabs may exist at high elevations from strong northeast wind. Always keep in mind that cornices are large and fragile at this time of year.

The remainder of the snowpack is strong, consisting of hard snow and various melt-freeze crusts.

Check out these pointers if you are considering big objectives.

Terrain and Travel

  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Problems

Cornices

Cornices are large and looming at this time of year. Given their size, any failure is highly consequential. Stand well back on ridges and avoid travelling beneath them.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3
