Aspen

Steep wind-drifted slopes at higher elevations are the most problematic and likely places to trigger a large and deadly avalanche. Look for smooth, rounded features below ridges and cornices or stiff, hollow-sounding snow as indications of this problem. You might not get any signs of instability before the slope fails, so treat any steep open slope with caution. Lower-angle, wind-sheltered slopes are less risky options.
