2012 Map of Orrs Springs
USGS Topo · Published 2012About this map
Orrs Springs serves as the focal point for this interior Mendocino County landscape, where the headwaters of several major coastal drainage systems originate. The terrain is defined by prominent elevations such as Pine Ridge, Alaska Ridge, and the landmark Eagle Rock, which overlook a network of working ranches including Greenfield Ranch, Mann Ranch, and Eagle Rock Ranch. The area's industrial and ranching history is etched into the landscape through specialized routes like Masonite Industrial Rd and Running Springs Ranch Rd. Hydrologically, the sheet captures a significant divide, showing the easternmost reaches of the S Fork Big River and the complex system of the S Branch N Fork Navarro River, alongside numerous creeks like Ackerman Cr and York Cr that carve through the high ridges.
