Snowpack Summary
A surface slab continues to build on top of the well preserved and widespread Dec 17th surface hoar layer (10-20mm) down 40 to 65cm depending on wind loading. This SH layer sits on top of a rain crust up to 2100m on well settled snow above 2100m. The Dec 9th surface hoar layer is down 80cm in the area. The Nov 9th crust is 30cm up from the ground.
Avalanche Summary
Skier triggered, skier remote and natural avalanches continued through Dec 23. Remote triggering of the surface slab from distances greater than 50m were reported Dec 22. Most of the activity was occurring between 1700-2400m. Moderate to strong southerly winds will be continuing to transport storm snow and overload the Dec 17 surface hoar layer.
