    Forecasters have had easy test results on this layer recently. The tricky thing about this layer is that it is not widespread but can be found in sheltered areas.

Weather Forecast

Cool temps for the next few days, with freezing levels creeping up to treeline elevation on Friday afternoon. 10cm of snow expected to fall in the Columbia Icefield area by Sunday night.

Snowpack Summary

Recent warm temperatures and rain followed by cooler temps have produced a widespread crust up to 2400 on all aspects. Above this, previous wind affected surfaces in exposed areas and wind slabs on lee aspects.

Avalanche Summary

The avalanche activity has slowed with the cooler temperatures. Several small loose wet slides were observed today along the Endless Chain out of steep, rocky, solar aspects around 2100m.

Confidence

Intensity of incoming weather systems is uncertain
