Northspur and the former logging settlements of the Mendocino backwoods are the focal points of this 2015 survey. The landscape is defined by the complex drainage systems of the Noyo River and the S Fork Ten Mile River, where narrow gulches and steep ridges dictate the placement of early habitations. Longstanding names like Irmulco and Alpine reflect the area's history of timber harvesting and remote outpost living. Transportation through this dense terrain is largely confined to ridge-top routes such as Three Chop Ridge or valley-bottom paths like Northspur RD. The map reveals a high concentration of named physical features, from Riley Ridge to the deep Camp Ten Gulch, illustrating the granular geographic knowledge required for navigating and working in these coastal mountains. Settlement sites like Wanhala and Marble Place appear as small clearings within a predominantly vertical wilderness.
