Once one of the nation’s largest underground uranium mines, the Schwartzwalder Mine is located in Jefferson County northwest of Denver, Colorado.
Colorado Cotter Corporation acquired the Schwartzwalder Mine in 1965 and was operational until 2000. The uranium deposit was discovered in the 1940s and was developed as a multi-level, hard rock underground uranium mine.
Nearly every uranium operation studied in this report had environmental and/or labor violations. The following case studies -- taken from our publication, Nuclear Power's Other Tragedy: Communities Living with Uranium Mining -- highlight some of the most controversial uranium projects in the United States.
