Avalanche Summary
Avalanche activity has tapered off following last week's storms. A few small natural avalanches were reported on Sunday, mostly size 1-1.5 loose dry avalanches in the surface snow. On Saturday, explosive control in the Monashees produced a size 3 avalanche on a wind-loaded northeast ridge that scoured down to the late November crust. No recent human-triggered avalanches have been reported, but remain possible on specific terrain features such as wind-loaded slopes.
Snowpack Summary
Snow from last week's storms is settling and getting redistributed into fresh wind slabs by northwest winds. Roughly 30-60 cm of recent snow sits above various crusts from the warm weather in late November. Reports suggest the snow is bonding to the crusts so far, but there's potential for this layer to develop into a problem in the future. Snow depths decrease rapidly below treeline, where the primary hazards are rocks, stumps, and open creeks.
