Snowpack Summary

The snowpack summary for April 25th is a temperature crust on steep solar aspects. Sheltered locations may hold 5-15cm of spring powder snow over previous wind surfaces and crusts. Several thick and thin crusts exist in the upper snowpack depending on aspect, elevation, and angle. The middle of the snowpack is supportive and well consolidated.

Avalanche Summary

Maligne and Icefield's patrol on April 25th observed several loose wet avalanches up to size 1.5 mainly solar triggered. Consult the Mountain Information Network for recent observations, and please consider submitting a MIN report .

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

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.
