Regions

South Rockies, Akamina, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West.

Head to high north facing slopes to find the best conditions.

Please submit any observations or photos from your travels to the MIN.

Confidence

Moderate

Avalanche Summary

Over the weekend, small wet loose avalanches were reported to size 1.

And on Friday, skiers remotely triggered a slab on a northeasterly lee ridge feature at treeline near Mt. Fisher.

Snowpack Summary

The snow surface is likely a crust at higher elevations, transitioning to moist snow as you move below 2000 m. High alpine north facing slopes may still hold dry snow above a thick crust from late March.

The snowpack is quickly disappearing below treeline.

Weather Summary

Monday Night

Cloudy with light flurries possible. 30 to 50 km/h southwest ridgetop wind. Freezing level above 2000 m.

Tuesday

Cloudy with flurries. 30 to 50 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 2000 m.

Wednesday

Mostly cloudy with flurries. 20 to 30 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level around 2000 m.

Thursday

Clear skies with 20 to 30 km/h southwest ridgetop winds. Freezing levels rise towards 2300 m.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
