Avalanche Summary
Reports on Saturday include several natural and human triggered storm slab, loose dry and wind slab avalanches to size 1.5.On Friday, there were reports of human triggered storm slab avalanches up to size 2. There were also reports of a natural avalanche cycle to size 2.5 in the neighboring Glacier National Park region.
Snowpack Summary
10-30 cm of recent storm snow is sitting mainly on wind slabs and facets (sugary snow), as well as surface hoar (feathery crystals) in sheltered areas and a crust on sun exposed slopes. There are a two weak layers in the upper snowpack that were buried in mid and late January. These can be found approximately 40-80 cm deep. Both layers consist of surface hoar and may be associated with a crust on steep, south facing slopes. These weak layers have been most reactive at lower elevations. Avalanche occurrences on these layers have tapered significantly, however it may still be possible to trigger an avalanche on these layers in isolated areas such as steep cutblocks and large open glades.The lower snowpack is generally considered to be strong, except for shallow, rocky areas where the cold temperatures continue to facet (weaken) the snowpack.
