Snowpack Summary

New snow is landing on a medley of snow surfaces including hard and soft wind slabs, scoured slopes, blue ice and thin melt-freeze crusts. Winds are likely to shift snow into slabs in the lee of terrain breaks such as ridges and ribs. Surface hoar layers buried in the upper snowpack are patchy in their distribution. Recent snowpack tests recently gave generally hard to no results near Smithers. An otherwise strong mid-pack overlies a weak base layer of facets/depth hoar. The snowpack depth is around 100 cm at treeline.
