When founded in 1896, Superior took its name from the quality of the coal it mined. What made that coal “superior” to the other ores mined in Colorado’s Northern Field? Learn how Superior’s geology shaped our history at the Historic Commission’s Annual Fall Program. Jeff Graves, Director of Inactive Mine Reclamation Program, Division of Reclamation, Mining and Safety, Colorado Department of Natural Resources, will present an overview of local geology, how it influenced the mining industry, and how inactive mines still play a role in the environment today.
