2012 Map of Omo Ranch

About this map

Omo Ranch and the surrounding Sierra Nevada foothills are defined by a complex drainage system where the Steely Fork Cosumnes River, Middle Fork Cosumnes River, and S Fork Cosumnes River carve through the landscape. This 2012 survey illustrates the transition from historic mining activity to modern forestry and rural residency. Signs of the area's industrial past remain visible through features like Henrys Diggings, Loveless Dredgings, and the Andreason Mill. Local history and genealogy are anchored by several notable sites, including the Indian Diggins Cem near Marble Springs and the Andreason Cem further south. The map details a network of ridges and gulches, such as Farnham Ridge and Slug Gulch, alongside small settlements like Brownsville and the high-elevation Leoni Meadow. Water resources are central to the terrain, featuring the Big Reservoir and Little Reservoir along the winding Indian Diggins RD.
