Geology Museum

The Colorado School of Mines Geology Museum, home to one of the state’s two Goodwill moon rocks collected during the Apollo 17 mission, was started in 1874 and displays mineral, fossil, gemstone, meteorite and historic mining artifact exhibits on two floors.

The museum serves as the state repository for Colorado’s mineral heritage and promotes its importance and understanding to the university community and the public. It aims to inspire scientific curiosity through education and research while encouraging appreciation of the earth and responsibility for its mineral, fossil, meteorite, and historic mining treasures.

Discover Mines’ Hidden Gem

The Mines Geology Museum contains extensive displays of minerals, mining artifacts, meteorites, fossils and gemstones as well as a walk-through mine. Founded in 1874, our displays now include over 2500 cataloged specimens and occupy two floors in the modern General Research Laboratory building at Mines.

Highlights include an introductory video about area geology and displays about critical materials and ultraviolet minerals. Apollo 15 and 17 moon rocks as well as the Miss Colorado Crown can also be viewed. Murals originally exhibited at the Golden Gate International Exposition in 1939 by artist Irwin Hoffman depict the history of mining and can be seen in the main gallery. Rotating exhibits are also on display because we strive to change 20 percent of our displays annually. An outdoor geologic trail features outcrops containing fossilized dinosaur tracks, logs and leaves.

Mines Geology Museum has the most extensive collection of Colorado mineral specimens. We are the first university to receive a moon rock on loan from the Johnson Space Center in Houston. In 2018 we had over 27,000 visitors from all 50 states and over 40 foreign countries.
