Snowpack Summary
Deep persistent, melt-freeze crust/facet combo remains the primary concern, with an average depth of 20 to 50cm deep at tree line. This crust (Oct. 25) is expected to linger in the snowpack for sometime. Very few options for travel on skis BTL (1900m) due to low snow cover, open creeks or hidden, early season hazards.
Avalanche Summary
This previous week the Oct 25 layer has produced some large natural avalanches (up to size 2.5) through the Rockies from as far south as Kananaskis Country, north to Yoho, the Icefields, Jasper and Marmot Basin Ski Hill. Best to presume all skiable slopes have this layer and dig to assess the strength of the bond before committing to the line.
