Points saillants

Extremely cold temperatures will make travel slow and the ice hard and brittle. Bundle up and watch your partners for frostbite.

    This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.

Weather Forecast

Expecting Tuesday to grace us with possibly the coldest temperatures of the season so far (forecasted to lows of -35 overnight in the ice fields area)! We should see a warming trend as we move into the weekend and continued sunshine to help soften the bite of the temperatures.

Snowpack Summary

Surface facetting due to extremely cold temps. Hard mid-pack is providing bridging strength over the weak basal facet layer at tree line and above. Recent settlement below tree line has greatly improved travel. Reasonable ski conditions can be found in sheltered features at tree line and below.

Avalanche Summary

No new avalanches reported today.
