Steamboat & Flat Tops

You can trigger an avalanche where strong winds on Thursday drifted snow into soft slabs on easterly and south-facing slopes at upper elevations. Avoid any steep area where you find more than about 10 inches of recently drifted snow. You can trigger larger, more dangerous avalanches in these areas.

Look and avoid areas where you see evidence of recent wind-drifting, such as round pillows of snow, fresh cornice growth, and drifts on the lee side of rocks and trees. Stick to wind-sheltered slopes.
