Grand Mesa

On upper-elevation slopes, you can trigger an avalanche where westerly winds drift snow into lens-shaped pillows. Avoid these pillows below steep ridgelines, rollovers, and on the sides of gully features. If you notice cracking or collapsing in the new snow, move to sheltered slopes less than about 35 degrees. If you are on a ridgeline give cornice features a wide berth and avoid traveling beneath them.
