Aspen

You are most likely to trigger larger, more dangerous avalanches at upper elevations on steep, northerly, and easterly-facing aspects. Be especially careful in steep couloirs and just below ridgelines where slabs are thicker. Signs of danger include smooth, rounded pillows of snow, fresh cornice growth, and cracking in the new snow. If you experience any of these conditions, find a more wind-sheltered or lower-angle place to ride. Stay off steep slopes above terrain traps, such as cliff bands or trees.

Be careful if you are walking up steep couloirs. You may walk into wind slabs as you get closer to the top.
