About this map

Dutchmans Knoll rises above a complex drainage system in Mendocino County, where the various branches of the Ten Mile River converge. This 2012 survey illustrates a landscape defined by sharp ridges and deep gulches, including Buckhorn Ridge and Smith Ridge. The topography is shaped by the Middle Fork Ten Mile River, N Fork Ten Mile River, and S Fork Ten Mile River, which slice through the terrain alongside numerous named ravines like Horsetail Gulch and Vallejo Gulch.

Evidence of historical land use appears at O'Conner Orchard in the north, while the road network is limited to utility and access routes such as Camp One Ten Mile Rd and Camp Two Ten Mile Rd. These routes follow the river valleys, reflecting the area's history of logging and resource management. The map serves as a detailed record of this coastal watershed's physical geography, from the heights of Ramsey Ridge to the winding course of Smith Cr.
