Conditions may be improving, but be mindful of the recent reports of 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 110 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.
A helicopter landing on a slope remotely triggered several size 2 persistent slab avalanches on a north aspect in the alpine south of Golden on Friday. The avalanches failed on the crust which was down 80 to 110 cm in that location.
A second heli remote triggered size 2 persistent slab avalanche was reported at another operation on a north facing slope at treeline. The crust was down around 60 cm in that location.
0 to 10 cm of recent snow overlies predominantly crusty surfaces.
A widespread crust with sugary facets above is down 40 to 110 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. However, when a thick surface crust is present, human triggering this layer is unlikely.
The bottom of the snowpack is generally weak and faceted, with the potential to produce very large avalanches. The most likely areas to trigger this deeply buried weak layer are steep, rocky areas in the alpine with a shallow or thin to thick snowpack.
