You could trigger a small avalanche on steeper slopes with fresh wind-drifted snow above weaker, softer snow. Triggering an avalanche from a deeper drift could break deeper and wider than you might expect. Use caution below ridgelines, on the sidewalls of gullies, or downhill of steep rollovers where you see lens-shaped pillows of snow or the snow surface feels hard under your feet. Even a small avalanche can knock you over and become dangerous if you get pushed into rocks, over trees, or stuffed in a gully. You can find safer travel on slopes without wind-drifted snow or those less than about 30 degrees steep.
