2011 Map of Placerville

About this map

The Boise Basin reveals a landscape defined by its deep mining heritage, centered on the historic settlements of Placerville and Quartzburg. This area, once a focal point of 19th-century gold fever, retains numerous named mining sites such as the Gold Hill Mine, Mineral Hill Mine, and Iowa Mine. The geography is characterized by a dense network of gulches—including Confederate Gulch, Illinois Gulch, and Slaughterhouse Gulch—which served as the primary locations for placer operations like the Leary Placer Mine. Drainage systems such as Grimes Creek and Granite Creek provided the essential water for these ventures. While New Centerville and the Star Ranch Summer Home Area indicate more modern residential uses, the presence of landmarks like Mud Flat and Huckleberry Flat alongside the old road networks of Grimes Pass Rd and Old Centerville Rd preserve the historical footprint of the region's resource-driven development.
