Avoid shallow rocky areas where you may trigger buried weak layers.
Manage your sluffing around terrain traps as recent snow will not have bonded well to the existing snowpack.
A layer of surface hoar is buried 60 to 100 cm deep. This layer may be triggerable by riders at upper elevations where it is not bridged by a thick overlying crust.
There have been no new avalanches since the weekend.
Small (size 1) loose dry avalanches have been easily triggered by ski cuts in the new snow on Sunday.
Explosive control work near Revelstoke on Saturday produced cornice and near-surface slab avalanches, size 1.5 to 2.5.
Our most recent snow, 5 to 10 cm in most areas and up to 20 cm in the west Monashees may be poorly bonding to old surfaces. These include crusts, surface hoar, and facets.
The mid snowpack contains a couple of layers of note; a hard crust formed by an early December rain event around 60 cm deep and a layer of surface hoar 60 to 100 cm deep. Where it exists, the crust may shield underlying weak layers (buried surface hoar) protecting them from human triggering. Where the crust is not prominent, this buried surface hoar is a major concern.
The lower snowpack is variable throughout the region; in shallower snowpack areas, basal facets may exist. To learn more, check out our blog.
