Regions

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

It's a good time to explore more complex terrain.

Be sure to verify conditions and remain cautious when travelling on or under corniced ridges.

Avalanche Summary

No recent avalanches have been reported.

With limited observations this time of year, sharing your photos and observations on the Mountain Information Network helps everyone stay informed.

Snowpack Summary

A dusting of new snow is falling on a well-settled and strong snowpack, with a typical spring diurnal pattern in effect. Daytime warming moistens the upper snowpack, and overnight cooling usually forms a hard crust at higher elevations. Lower elevations may not refreeze and are melting out quickly.

Terrain and Travel Advice

  • This is a good time for exploring terrain.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
  • 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.
