The Pleasant View Roadless Area, located in eastern Los Angeles County approximately 17 mi northeast of Pasadena, California, was studied. The study included a geochemical survey and geologic mapping, and an examination of mines and prospects. There are no known mineral deposits and no evidence of past mineral production from the roadless area. Nevertheless, the geochemistry and mineralogy of stream sediments indicate that occurrences of the tungsten mineral scheelite are present. A probable mineral-resource potential for tungsten is assigned to this specific area. No potential for other mineral or energy resources was identified.
