1998 Map of Hoffstadt Mountain
USGS Topo · Published 2003About this map
The Mt St Helens State Wildlife Area and the surrounding landscape on this 1998 survey reveal a terrain fundamentally altered by geologic forces. Following the massive eruption of 1980, the North Fork Toutle River corridor is dominated by a significant Mud Flow deposit, a stark feature that defines the valley between the Toutle Mountain Range to the south and Hoffstadt Mountain to the north.
