1958 Map of Jericho Valley

About this map

Jerusalem Valley and Jericho Valley define the interior of this 1958 survey, where the drainages of Putah Creek and its many tributaries carve a complex series of ridges including the Watson Range and Bishop Mountain. The map documents a period of ranching and early resource extraction, noting the Red Elephant Mine near Oat Hill and the active Quarry in the north. Settlement is sparse and focused on established agricultural holdings such as Hennesey Ranch and Ink Ranch. In the southwest, a large Military Reservation sits adjacent to localized water bodies like Wildcat Lake and McCreary Lake. The landscape is notable for its distinct terrain features like the colorful Hells Half Acre and the expansive wooded area identified as The Cedars, showing the region before modern development patterns altered the rural character of the Lake and Napa county line.
