| Description |
English: The twisted girders of a highway bridge lie entombed in mudflow deposits from Mount St. Helens. This May 18, 1980 mudflow was produced by dewatering of the debris-avalanche deposit in the North Fork of the Toutle River and traveled as far as the Columbia River, decreasing the depth of the navigational channel from 11 meters to 4 meters. |
