The 2012 Tunnel Creek avalanche occurred in the northwest United States on February 19, 2012. It happened at about noon PST in the Tunnel Creek section of Stevens Pass, a mountain pass through the Cascade Mountains of Washington, at the border of King and Chelan counties.[1] There were three fatalities and one injured.

The avalanche was characterized as a slab avalanche, or 200 feet (60 m) across and three feet (0.9 m) deep.[2] Three days before the avalanche occurred, a large snow storm dumped 32 inches (0.8 m) into Stevens Pass, which resulted in the unstable snow pack that was disrupted by skiers on their excursion.
