Northern San Juan

You are most likely to trigger an avalanche in wind-affected areas. Avoid traveling near common trigger points including convex rollovers, rocky outcrops, or the edges of slopes where the margins of a slab are the thinnest. You could trigger an avalanche from below, and avalanches could break deeper and wider than you expect. Give yourself a wide buffer from suspect slopes steeper than around 35 degrees. You may not experience obvious signs of instability before triggering a dangerous avalanche.
