1952 Map of Omo Ranch

USGS Topo · Published 1986

About this map

Omo Ranch and the historical Brownsville settlement area anchor this mid-century topographic record of the Eldorado National Forest in California. The landscape is heavily defined by its 19th-century gold and copper mining heritage, centered around the sprawling Henrys Diggings and numerous individual operations like the Cosumnes Copper Mine, Caldor Mine, and Washington Mine. These mining sites are concentrated along the complex drainages of the Middle Fork Cosumnes River and its many tributaries, including Sopiago Creek and Slug Gulch.
