Highlights

Early season hazards due to the shallow snowpack (skiers) and thin, newly formed ice (climbers) remain a primary concern.

    Best to assume all skiable slopes have this layer, and assess the strength of this interface before committing to a line.

Snowpack Summary

The Oct. 25th crust/facet combo remains the main concern. This layer is buried an average of 20 to 50cm, and is present on most slopes with sufficient snowpack for safe skiing - we expect this layer to linger for sometime. The snowpack below treeline is mostly below threshold depths for avalanche activity.

Avalanche Summary

Last week the Oct 25th layer produced some large natural avalanches (up to size 2.5) throughout the Rockies from as far south as Kananaskis Country, north to Yoho, the Icefields, Jasper and Marmot Basin Ski Hill.
