Sustained strong winds have created stubborn slabs of wind-drifted snow on upper-elevation slopes and terrain features. These drifts could be 1'-3' deep and up to 150' wide. Watch for and avoid signs of wind-drifted snow; such as pillow-shaped deposits and rounded smooth areas of snow. Cracking in new wind-drifted snow is a sign that things are unstable and steeper slopes should be avoided. Cornices are signs of wind loading leeward features. Any cornice failure could trigger an avalanche on the slope below.
