About this map

The Pacific coastline at Fort Ross and the Northwest Cape anchor this mid-century survey of coastal Sonoma County. The map documents the area during the early 1940s, highlighting the Fort Ross State Historic Monument along the rugged shore where the Pacific Ocean meets the cliffs. Inland, the landscape is defined by a series of prominent ridges, including Muniz Ridge, Creighton Ridge, and Kings Ridge, which dictated the early settlement and transportation patterns of the region.

Resource extraction and early ranching are evident through features like the Murphy Mill (Abandoned) and the Manganese Mine (Inactive). Small community centers are represented by the Creighton Ridge Sch and the Seaview Cem, while family-named properties such as Seafeldt Ranch and Toners Place reflect the rural character of the era. The complex drainage systems of the South Fork Gualala River and Russian Gulch illustrate the steep, dissected terrain that has historically isolated this stretch of the California coast.
