Snowpack Summary
In general, snowpack depths are below seasonal average any many slopes below treeline are reported to be below threshold for avalanche activity. Deeper snowpacks may exist to the north of the region.Dribs and drabs of recent snowfall overlie weak faceted crystals, small surface hoar or older hard windslabs in exposed high elevation terrain. These modest accumulations may have been shifted into small pockets of windslab in areas where winds have been stronger.Between 35 and 50cm below the surface you may find a weak layer of surface hoar on sheltered slopes and a melt-freeze crust on steep solar aspects. Most reports indicate this layer is "stubborn" to trigger, or there may not be a deep enough overlying slab to create a significant hazard. That said, I'd remain curious about this interface, especially as the snow load increases.There are reports of a deeply buried early season crust which may have associated facets. This layer is more likely to be found in the high alpine on northerly aspects. Little is known about its reactivity in this region.
