Avalanche Summary

Numerous slab avalanches were seen from the Icefields Parkway on Friday when the storm ended. Most had occurred in steep alpine terrain, and the largest were up to size 3, running surprisingly far into lower elevation terrain that has minimal snow cover.

Snowpack Summary

The snow pack is highly variable across the region with the deepest zone being around the Icefields, which has about 60 to 80 centimeters at tree line. Since the end of the storm on Friday, moderate SW winds have continued to transport snow in open areas. There is not yet much information available about the early season snowpack structure, so be sure to dig down and investigate if you're heading out, and post your observations to the MIN!
