Regions

South Coast, Powell River, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron.

Cornices may be difficult to identify from the top of a ridge, so it's best to keep a safe distance when traveling along ridgelines. Learn more about spring snowpack conditions here.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported on Monday.

Evidence of past avalanches, like this one observed Saturday on Sky Pilot, may still be visible in the region.

NOTE: Recent observations are currently very limited in this region.

Make observations and continually assess conditions as you travel.

Snowpack Summary

A typical spring diurnal cycle is underway.

High freezing levels have formed a surface crust everywhere.

The snowpack is generally well-settled and strong.

Lower elevations are melting out rapidly.

Terrain and Travel Advice

  • Avoid travelling on slopes below cornices.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Make observations and continually assess conditions as you travel.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
