Snowpack Summary

New snow will accumulate over a variety of surfaces including; surface hoar in sheltered terrain, A crust on south aspects and all aspects below treeline and old wind effected surfaces in exposed terrain.

A widespread crust exists 25-40 cm below the surface, and surface hoar has been found above the crust in some parts of the region.

The remainder of the snowpack is well settled. Conditions remain rugged at lower elevations.
