1985 Map of Thousand Lakes Valley

About this map

Lassen National Forest and the Thousand Lakes Wilderness define this high-altitude landscape in Shasta County. The terrain is dominated by volcanic features, including the Devils Garden lava flow and the prominent Magee Peak, which stands as a central landmark topped by the Magee Lookout. The area's glacial and volcanic history is evident in the dense concentration of small mountain lakes, such as Lake Eiler, Upper Twin Lake, and Hufford Lake, which dot the Thousand Lakes Valley. This map captures the mid-1980s state of the wilderness before significant modern forest management changes, showing a primitive road network and isolated resources like the Cinder Pit near Bear Wallow Butte. Water sources including Cornaz Spring and Wilcox Spring are noted alongside deep drainage features like Logan Gulch.
