You could trigger avalanches in wind-drifted snow on slopes just beneath ridgelines, in cross-loaded gullies, and downhill of steep, convex rollovers. You can trigger these avalanches from below or from a distance. Observers report avalanches running into usually “safe spots.” You may not see signs of instabilities like cracking or collapsing before triggering a large avalanche. You can find safer travel by sticking to slopes less than 30 degrees.
