Maps and interpretation of geochemical anomalies in the John Muir Wilderness, Fresno, Inyo, Madera and Mono counties, California

January 1, 1994

A geochemical survey of the John Muir Wilderness was conducted by the U.S. Geological Survey between 1969 and 1978.  The 755-mi2 (1,956-km2) wilderness is located in the central Sierra Nevada, Calif. (fig. 1). Stream-sediment samples were collected at 1,434 sites in the wilderness and immediately adjacent areas.  Analytical data for these samples and a map of smapling sites are presented by du Bray and Dellinger (1980) and Diggles and others (1981).  A geologic map of the area was compiled by du Bray (1981).  These maps and tables present the results of the analysis of geochemical data for lead, zinc, gold, silver, arsenic, chromium, molybdenum, manganese, tungsten, tin, copper, and nickel.  These are elements of economic interest which have historically been found in mineral deposits of the Sierra Nevada or other geologically similar areas.
