Southern San Juan

Fresh wind-drifted slabs stacked above weaker, faceted snow increases your chance to trigger a large avalanche, and some may run naturally. An avalanche triggered near the surface could step down into weak snow layers several feet deep on slopes facing west through north to east. The deeper the avalanche breaks, the more likely it is to span adjacent terrain features and will be a challenge to escape. Avoid slopes steeper than about 30 degrees with about 10 inches of drifted snow, or places with a smooth, pillowy appearance.

If you see shooting cracks, hear loud collapses, or transition from soft to harder snow, choose an alternative route or different slope. Southerly and east-facing slopes below treeline without steep overhead hazards offer safer travel options.
