Manganese prospect · Trinity County, California
discovered 1941
Drawn as an open-pit mine, dug down in benches from the surface. 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.
