About this map

Omo Ranch and the surrounding timberlands of the Eldorado National Forest define this 2018 survey of the Sierra Nevada foothills. The landscape is deeply carved by the Middle Fork Cosumnes River and the S Fork Cosumnes River, which dictate the rugged orientation of the local ridgelines. Evidence of historical transport and resource management is visible in the Diamond Railroad Grade and the numerous named gulches like Slug Gulch and Drummond Gulch, which speak to the area's legacy of mining and logging.

Local landmarks such as the Andreason Cem and Marble Springs provide specific points of interest for genealogical and local history research. The presence of water infrastructure, including Big Reservoir and Little Reservoir, highlights the critical role of water management in this part of El Dorado County. This map serves as a modern record of the scattered settlements and natural features like Plummer Ridge and Gold Note Ridge before the shifts of the coming decades.
