You can trigger a large and dangerous avalanche on west to north through southeast-facing slopes. The most dangerous areas are where the snowpack is thinner such as near a rock outcrop, by a stand of trees, or towards the bottom of a wind-loaded slope. Thinner areas are more dangerous because it is easier for you to affect the deeply buried weak snow near the ground and trigger an avalanche from long distances away. If you do trigger one of these avalanches it could break wider and run farther than you expect, so give any steep slopes of concern a wide margin. You can find safer travel options on wind-sheltered sunny slopes that melted to the ground prior to the late-November storms or on smooth, uniform slopes where the weak layer is buried deeper than about three feet.
