Avalanche Summary
A few size 1 explosives triggered avalanches were reported in the region on Tuesday.Avalanche activity quieted down on Sunday, with humans and explosives triggering a few small (size 1) wind slabs in lee features at treeline and in the alpine. On Friday and Saturday, many small to large (size 1 to 2) slab avalanches within the storm snow were triggered naturally, by humans and with explosives. For examples, check out the MIN reports here and here.
Snowpack Summary
Another 20-35 cm of new snow fell between Tuesday morning and Wednesday morning. This brings total recent snowfall amounts to approximately 40-60cm. This new snow likely sits on a sun crust on south facing slopes and surface hoar (feathery crystals) in sheltered and shaded areas. Recent strong to extreme southerly winds will have redistributed the new snow, forming storm slabs. Expect to find deeper deposits of snow in wind loaded terrain.
