Snowpack Summary

Surface hoar is beginning to form on the surface as indicated in this MIN report from the adjacent Northwest Inland region. Surface hoar formation has also been reported from the Ningunsaw zone. 10-15 cm of recent storm snow is sitting on a thick, hard crust. In some locations there is an early season crust with facets near the bottom of the snowpack. Check out this MIN report from the Anderson Cabin near Terrace.There is an average of 70-120 cm of snow in the alpine. This decreases dramatically with elevation where the primary hazards are rocks, stumps and open creeks.We currently have very limited snowpack observations.
