RUBICON ROADLESS AREA, CALIFORNIA.

The Rubicon Roadless Area encompasses about 8 sq mi along the lower reaches of the Rubicon River, a major tributary of the Middle Fork of the American River that drains the west slope of the Sierra Nevada in eastern California. Based on mineral-resource surveys the area has little promise for the occurrence of metallic or energy resources. A very small demonstrated gold resource occurs at the Pigeon Roost mine. Glacial deposits, which occur in the eastern part of the area, are too bouldery and too small to be of value as construction materials.
