In sintesi

Recent settlement has generally increased the strength of our snowpack but pockets of Wind Slab exist at higher elevations. Lingering uncertainty about the ability to trigger deep persistent weak layer requires a cautious approach to terrain.

Snowpack Summary

Surface Hoar development 1600-1800m. Sun crust on solar aspects. 10-30cm Wind slabs in lee terrain over a strong, well-settled midpack. Facets and Depth Hoar at the base of the snowpack remain a concern in shallow snowpack areas.
