Aspen

The most dangerous areas are wind-loaded slopes, particularly gullies and couloirs, near and above treeline facing north, northeast, and east. Southerly-facing slopes and wind-sheltered slopes offer safer travel options.

If you are traveling on very steep, wind-sheltered slopes facing the north half of the compass you can trigger a small loose avalanche. Avoid traveling on shady slopes steeper than about 40 degrees above terrain traps such as a cliff or a creek where even a small avalanche can be dangerous.
