You can easily trigger a large and deadly avalanche. Recent strong winds deposited snow into thick slabs that rest on top of a weak layer near the ground. You can trigger these avalanches from a distance or below a steeper slope. Give yourself a wide margin around any slope steeper than 30 degrees. You can find safer travel at lower elevations on low-angle slopes.
