Avalanche Summary
A few small loose avalanches in very steep terrain have been reported since the weekend.
Otherwise, no new slab avalanches have been reported since a natural avalanche cycle late last week.
Snowpack Summary
Up to 50 cm of recent snow continues to settle and stabilize, with variable wind effects at higher elevations in exposed terrain.
While the mid and lower snowpack is generally well-settled, two crust/facet layers will be closely monitored as the snow load above continues to accumulate. These layers have a variable distribution and have not resulted in any recent avalanche activity.
