About this map

Putah Creek winds through a complex topography of ridges and valleys along the Lake and Napa County border in this late 1950s survey. The landscape is defined by remote ranches and specialized industry, notably the Red Elephant Mine near Oat Hill and the isolated Ink Ranch to the south. The mapping shows an area of significant land management, including a large Military Reservation and prominent natural features like The Cedars and Hells Half Acre.

Water resources are central to the terrain, with small upland bodies such as Amel Lake, Wildcat Lake, and McCreary Lake dotting the hillsides. Transportation in this era relied on a network of dirt routes and trails, including Morgan Valley Road and the Deep Trail, connecting disparate settlements like Jericho Valley and Jerusalem Valley. The presence of features like the Pumphouse and Round Corral suggests a continuing history of livestock and water infrastructure in this corner of the Coast Ranges.
