Travel and Terrain Advice

- Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.
Avalanche Summary
A few size 1- 1.5 storm slabs and loose dry avalanches were reported on Monday between 1250 and 1600 m.
Snowpack Summary
Around 20-30 cm snow overlies various surfaces including a freezing rain crust (which was reported as being hard in the alpine and breakable below treeline), old sun crusts and wind slabs.
A variable weak layer that formed in mid-December can be found in the upper snowpack. This mid-December layer is comprised of crusts on solar aspects and feathery surface hoar in sheltered locations.
The lower snowpack is generally well settled with two prominent crusts. The late-November crust can be found 30-50 cm below the surface and the October crust is near the base of the snowpack.
