2021 Map of Orrs Springs

About this map

Orrs Springs serves as the focal point for this survey of the Mendocino interior, where the headwaters of several major California watersheds converge. The landscape is defined by its deep drainage networks, including the S Fork Big River and the S Br N Fork Navarro River, which carve through the prominent topography of Pine Ridge and Alaska Ridge. This era of the region's development is marked by a complex network of ranch and timber access roads, such as Masonite Industrial RD and Running Springs Ranch Rd, tracing the ridgelines and creek beds. The cartography reveals a transition from the steeper canyons near Eagle Rock to the lower elevation crossings of Ackerman Cr and Orrs Cr. Notable for local history researchers are the numerous private named roads like Fred Macmurray Ln and Brandywine Dr, which indicate the evolving residential and commercial footprint in these remote hills.
