  • The May 18, 1980 debris avalanche from Mount St. Helens covered over 24 square miles (62 square kilometers) of the upper Toutle River valley and blocked tributaries of the North Fork Toutle River. New lakes such as Castle Lake (pictured here) and Coldwater Lake were created. Scientists and engineers estimated that a breach of the debris dam at Castle Lake could unleash mudflows and floods comparable to those triggered by the May 18, 1980, eruption of Mount St. Helens. USGS Photograph taken on June 25, 1980, by Tom Casadevall.
