About this map

Fort Ross and the immediate Sonoma coastline appear in 1944 as a landscape defined by ranching, resource extraction, and early heritage preservation. The Fort Ross State Historic Monument marks the site of the 19th-century Russian settlement, while the surrounding hills are punctuated by family-named holdings like Seafeldt Ranch and Happy Hill Ranch. The presence of the Layton Mine and an inactive Manganese Mine points to the area's strategic mineral importance during the war years.

Industrial activity is also visible at the Murphy Mill, which is noted as abandoned by this date. The rugged interior is carved by the Gualala River and its various forks, supporting small rural nodes like the Creighton Ridge Sch and the Seaview Cem. Long ridges such as Mohrhardt Ridge and Kings Ridge dominate the topography, illustrating the challenging terrain that shaped early Northern California coastal development.
