Steep wind-drifted slopes at higher elevations are the most dangerous and likely places to trigger a large and deadly avalanche. The upper end of the near-treeline band into the alpine, where thicker slabs have formed, is where you need extra caution. You might not get any signs of instability before the slope fails. Look for smooth, rounded features below ridges and cornices or along gully walls as features to avoid. Lower-angle, wind-sheltered slopes are less risky options.
