Mines Museum, home to one of Colorado’s two Goodwill moon rocks collected during the Apollo 17 mission, had its beginnings in 1874 with the collection of geologist, Arthur Lakes, and includes the historic Colorado State Mineral Collection created by the Bureau of Mines in the 1890’s. The museum serves as the state repository for Colorado’s mineral heritage and showcases the most extensive public collection of minerals from Colorado.
