1982 Map of Trinity Dam

USGS Topo · Published 1982

About this map

Trinity Dam and the sprawling waters of Clair Engle Lake dominate this 1982 provisional study of the California mountains. The landscape is defined by the transformation of the Trinity River canyon, where the massive dam and its associated Powerplant replaced earlier canyon floor settlements. Traces of the region's mining heritage remain visible through several named sites, including a Hydraulic Mine near Stuart Fork Picnic Area and smaller operations like the Buckeye Mine and Little Elsie Mine tucked into the steep drainages of the Trinity National Forest.
