Avalanche Summary
Sporadic cornice falls have occurred over the last week, some triggering slabs on the slope below. Otherwise, no new avalanches have been reported.
Snowpack Summary
Large cornices overhang alpine slopes and threaten to trigger avalanches on slopes below. Recently formed wind slabs may be isolated to alpine wind-loaded terrain. In many places, the snow surface consists of a crust or moist snow and the snowpack is generally strong. Deeply buried weak layers near the ground are becoming hard to find, but may remain sensitive to triggering from thin snowpack areas or with large loads such as cornice fall.
