1958 Map of Jericho Valley

About this map

Putah Creek winds through the heart of this mid-century survey, defining a landscape marked by ranching, mining, and complex county boundaries. The intersection of Lake, Napa, and Yolo counties occurs in the high ground above Jericho Valley, where isolated operations like the Red Elephant Mine and various quarries suggest a history of resource extraction. Local family influence is evident through established locations such as Hennessey Ranch and Ink Ranch, while landmarks like Jim Dollar Mtn and Petticoat Mtn rise above the drainage basins.
