Avalanche Summary
No avalanches have been reported recently in the Cariboos. In the neighbouring North Columbia region, a large natural slab failed on a deeply buried weak layer.
Snowpack Summary
You may encounter soft wind slabs near ridge tops, which could be sensitive to the weight of a person. As winds shift from southerly to northerly, be alert to the possibility of finding wind slabs on all aspects. Older wind slabs may be hidden under recent new snow.In sheltered areas, 10 -15 cm light dry snow has buried large surface hoar crystals. I'm unsure how widespread the surface hoar is across the region. 20-30 cm settled, dried-out powder lies below this. The mid- and lower snowpack are reportedly well settled. The early December weak layer (about a metre down) is now unlikely to be triggered, except perhaps with a very heavy trigger. At the base of the snowpack, on high north aspects, basal facets overlie glacial ice.
