The Yankee John mine.

The Yankee John mine was located by miners in 1858, part of the Centerville mining district near Redding, Shasta County, California. It had various owners through the years. Between 1926 and 1932 the Yankee John mine yielded $83,000 worth of gold. The mine was abandoned in 1962.  It's still an intriguing place to visit west of Redding via Placer/Simmons Road. BLM maintains this historical mining site.
