1983 Map of Hoffstadt Mtn

USGS Topo · Published 1984

About this map

The North Fork Toutle River valley undergoes a profound transformation in this 1983 survey, which documents the scarred landscape following the 1980 eruption of Mount St. Helens. Extensive zones of Mud Flow and massive areas of Blowdown dominate the river corridor, illustrating the immense power of the volcanic event. To manage the shifting sediment, engineering works like the Toutle Dam and the Debris Dam Earth Fill appear as critical infrastructure projects.
