1967 Map of Plaskett Ridge

USGS Topo · Published 1969

About this map

The Mendocino National Forest defines this high-elevation landscape, where the Black Butte River carves through complex ridges in both Mendocino and Glenn counties. During the mid-1960s, this area remained largely remote, accessible by a network of pack trails and jeep paths that linked isolated landmarks. Historic homesteads and administrative sites like Carpenter Place, Keller Place, and the Grizzly Flat Station suggest a legacy of high-country ranching and forest management. Physical landmarks such as Etsel Ridge and Plaskett Ridge dominate the topography, while smaller features like Coffee Mill Flat and Surveyors Flat provide evidence of early survey camps and localized land use. Water sources, including Keller Lake and O'Neil Spring, served as vital stops for travelers navigating between Thurmon Rock and the river valley below.
