1943 Map of Fort Ross

About this map

Fort Ross State Historic Monument stands as the primary coastal landmark on this Sonoma County survey, marking the site of the early 19th-century Russian settlement. The landscape is defined by its series of parallel ridges, including Mohrhardt Ridge, Kings Ridge, and Creighton Ridge, which dictated the early placement of ranching outposts and schools. Settlers navigated this steep terrain along routes like Sewell Road, establishing remote gathering spots such as the Trospers Club and Mc Kenzie Creek Club.
