Glacier.

The winter permit system is not yet in effect. Click here for information. Exposed rocks and trees are making dangerous travel conditions on approach trails below treeline and many obstacles are exposed at all elevations.

Weather Forecast

Today and Tuesday are forecast for mainly sunny with cloudy periods. Temperatures are returning to more normal values for this time of year and with this warming trend some snow is in the forecast for Wednesday and Thursday.

Snowpack Summary

Observations are limited. People riding in the Connaught drainage are reporting decent skiing in the high alpine but reports from the Asulkan are of thin and rocky conditions. The November 9 rain crust is down 40-50cm at 1900m and the snow above this crust is faceting in the cold and windy conditions. Snowpack below tree line is still very thin.

Avalanche Summary

No new avalanche activity since November 11th has been reported.

Confidence

Due to the number of field observations

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
