Marmoraton Mine

Discover the history of this abandoned open-pit iron mine that once employed 300-plus men who, between 1955 and 1979, filled 30 to 35 railway cars with iron ore each day. Wonder at the natural beauty that has since replaced this once-industrial land, where rainfall has filled the deep pit to create a lake that has a unique turquoise hue.
