Avalanche Summary

Recent skier-triggered avalanches just north of the forecast area indicate that triggering a large and dangerous slide is a very real possibility. Triggering a large slide is most likely where you find a shallow area of the snowpack. In shallower areas it is easier for you to impact weak, collapsible snow layers. Common trigger spots include rock outcroppings, steep rollovers, and below ridges and cliff bands. Recent winds have drifted snow onto west to north through easterly-facing slopes. Avalanches triggered here may be larger and break deeper.

Safer riding options exist below treeline or on low-angled, wind-sheltered slopes without steep overhead hazards.
