Snowpack Summary

At treeline up to 20cm of low density snow is overlying Nov 12th crust. Isolated wind slabs are present in the Alpine in lee and cross loaded features. There is an average of 50-60cm of snow at 2200m and this depth tapers quickly with elevation.

Wind Slabs

Wind slabs overlying the Nov 12 crust may be sensitive to human triggering. Use caution around ridge lines, gullies and cross-loaded terrain.

Caution in lee and cross-loaded terrain near ridge crests.Be careful with wind loaded pockets while approaching and climbing ice routes.
