Aspen

You can trigger small avalanches in wind-drifted snow just below ridgelines on easterly and south-facing slopes. Most of these avalanches will be small but on a consequential slope such as a couloir or a steep face with cliffs below you, they might prove dangerous. Identify wind-drifted terrain features by their rounded, wave-like snow surface appearance often found below a cornice on easterly slopes above treeline. If you notice cracking in the snow you've discovered a wind-drifted slope and should consider sticking to slopes less than about 35 degrees steep or find a less wind-drifted slope.
