Regions

Chic-Choc Mountains, Chic-Chocs.

Limit your exposure to steep, sun-exposed slopes, especially if you are sinking into the snow beyond ankle depth. As the snowpack warms and weakens, you should increasingly opt for safer terrain.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

No new avalanches have been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

In alpine terrain and at treeline, the snowpack is gradually transitioning toward an isothermal state. Below treeline, this process is complete, and you can easily sink up to your waist when you remove your travel equipment.

The snowpack continues to melt below treeline.

At mid-mountain, the average snowpack depth is around 90 to 120 cm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
