1967 Map of Thatcher Ridge

About this map

Mendocino National Forest defines the character of this rugged Northern California landscape, where the Middle Fork Eel River cuts through the western edge of the quadrangle. The map documents a wilderness dominated by steep elevations and high ridgelines, including the namesake Thatcher Ridge and Etsel Ridge. Within the sprawling Hayshed Basin, the terrain is marked by distinctive natural landmarks like Table Rock and Skunk Rock. Human activity in this remote region is limited to scattered outposts and high-altitude landings such as Hand Flat and the Barpes Ranch, connected by a network of 4WD trails. The intricate drainage system is well-defined, showing the headwaters of Hayshed Creek, Sallady Creek, and Mississippi Creek. This survey captures the Forest Service's management of the area in the late 1960s, prior to later re-mapping in the 1990s, preserving the locations of seasonal seeps and springs vital to local wildlife and early ranching interests.
