1986 Map of Mount Eddy

About this map

Mount Eddy and the surrounding Eddy Mountains dominate this high-elevation terrain within the Shasta National Forest. The landscape is defined by the headwaters of several major California waterways, including the North Fork, Middle Fork, and South Fork of the Sacramento River, alongside the early course of the Shasta River. This 1986 survey documents a complex hydrological system of alpine lakes and mid-century water management, including the Wood Diversion Dam and a Concrete Diversion Dam located near Morgan Meadows. The boundary between Siskiyou and Trinity counties runs directly through the western ridges, separating high-altitude features like Deadfall Lakes and Toad Lake from the eastern drainage basins. Dozens of 4WD trails and forest service roads crisscross the slopes, reflecting the mid-1980s infrastructure for recreation and resource management in this remote section of the Klamath Mountains.
