Manganese prospect · Trinity County, California
discovered 1942
Drawn as a prospect: a shallow pit or trench dug to test for ore, not a working mine. The ore color stands for manganese. Federal records note the kind of operation and its status, not its depth or layout, so this is a typical example rather than a survey of this site.
