You could trigger an avalanche in freshly drifted snow on steep slopes at upper elevations. Areas of drifted snow often look smooth and rounded. Avoid steep slopes where you observe 8 inches or more of drifted snow. Cracking in the snow surface is an obvious sign of instability and a good indication of stable slopes.
You can find safer travel on slopes less than 35 degrees, and areas protected from the wind.
