A skier triggered size 1 persistent slab avalanche on a small convex feature southest of Bralorne. The weak layer was down 50 cm and suspected to be the surface hoar/facet layer that was buried in mid-January. This layer has been largely dormant but may become active in isolated locations where the weak layer is well preserved. Continue to dig down and test this weak layer to monitor its reactivity.

35-50 cm(lower amounts in the north) of recent storm snow has buried a wide variety of old snow surfaces including stiff wind slab or wind effected snow at upper elevations, sun crust on steep southerly slopes, surface hoar and surface facets in sheltered locations. The mid-January surface hoar and facet interface is now buried 50-80 cm and the mid-December facets down 90-120 cm remain a concern especially in shallower snowpack areas like the Duffey, Hurley and/ or South Chilcotins. These deeper weaknesses warrant monitoring especially through periods of more load. In southern areas (Coquihalla), the lower snowpack is reportedly well settled(stronger), than it is to the north.
