1967 Map of Thatcher Ridge

USGS Topo · Published 1969

About this map

The Mendocino National Forest defines this high-elevation landscape, where the Middle Fork Eel River cuts through the western edge of the quadrangle. The 1967 field check reveals a network of high ridges and deep drainages, notably Etsel Ridge and Thatcher Ridge, which divide the waters of Hayshed Basin and Jack Hollow Creek. This era of the forest was marked by specialized access, with the Old Man Ridge Trail and Camp Meeting Ridge Trail providing the primary routes through the timbered terrain.
