2021 Map of Northspur

USGS Topo · Published 2021

About this map

Northspur and the winding Noyo River corridor define this region of the California Coast Ranges, where steep drainages and timbered ridges dictate the movement of roads and settlements. This 2021 survey shows a landscape deeply shaped by its logging and transit heritage, evidenced by locations such as Irmulco and the remote Alpine settlement. Long ridgelines like Sherwood Ridge and Chamberlain Ridge separate the various forks of the river system, while historical transportation corridors like the Fort Bragg-Sherwood Rd and Three Chop Rd follow the high ground to connect isolated valley outposts. The map reveals an intricate network of forestry roads and gulches, including Camp Ten Gulch and Arvola Gulch, providing a modern record of the geographic features that have supported the Mendocino county interior for generations.
