Cooling temperatures are reducing the likelihood of triggering large persistent slab avalanches.
Avoid steep or convex terrain features with a shallow or thin-to-thick snowpack.
A crust with weak facets above is down 40 to 130 cm. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places to trigger this layer.
No new avalanches were reported on Wednesday, but data is very limited in this region.
If you go out into the backcountry, please consider posting your observations on the Mountain Information Network.
0 to 5 cm of new snow overlies predominantly crusty surfaces.
A widespread, hard crust down 40 - 130 cm with weak facets above continues to be the primary layer of concern for human triggering of very large persistent slab avalanches.
