**NEW** Area closures for avalanche control are in effect intermittently from November to May. If not described in the bulletin headline below, the area is open. For more information and maps, click the link below under "Resources".
In general there is more storm snow overlying the Dec 7 layer of surface hoar, facets, and sun crust depending on aspect and elevation. In particular, there was large surface hoar noted prior to the last storm.
The Nov 5 crust has facets above and below it, and exists up to 2500m on shady aspects and higher on solar aspects. We haven't seen any activity on this layer since the storm, but the new load may have made it more reactive in some areas.
Deep persistent slabs are best managed by:
Cornices are best managed by:
High pressure will continue Friday with light winds, and no snow. Temperatures will continue to stay cool in the valley bottoms and in the alpine (-15C)
20-40 cm of low density new snow sits on the december 7th layer of sun crust, facets or surface hoar depending on your location. This new snow came with minimal wind and seems less reactive than we had thought it might be. At the bottom of the snowpack, the Nov. 5th crust / facet layer persists. Snowpack depths are 90-150 at treeline.
Limited observations from Little Yoho region. No new avalanches reported.
