Snowpack Summary

The snowpack has been below threshold depth for avalanches in the North Shore mountains and terrain below 1500m elevation. Incoming snow is not expected to bond well with a recently formed crust.In alpine areas near Squamish, up to of 70cm settled snow is on the ground. In these areas, a crust is lower in the snowpack, however it is now suspected to be well bonded to the overlying storm snow.
