Aspen

You can trigger a large and destructive avalanche on many northerly and easterly-facing slopes near and above treeline. If you trigger an avalanche here it might break on weak layers near the ground taking the entire season's snowpack down the mountain and growing into an unsurvivable avalanche. Avoid traveling on northerly and easterly slopes at these higher elevations, especially on shallow, rocky, uneven slopes where it is easier to impact buried weak layers.

You can also trigger a smaller but still dangerous wet avalanche on sunny slopes throughout the late morning and afternoon. If you start to see rollerballs and wet snow sticking to your feet, skis, or machine avoid steep, sustained slopes or slopes with terrain traps below you such as a creek or a cliff. Even a small loose avalanche can knock you over and take you for a dangerous ride.
