Geology Museum

Please note: The museum will be closed May 23-25 for Memorial Day. Regular hours will resume May 26 at 9 a.m.

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.

The main floor exhibits feature specimens from many Colorado mining districts, other global localities and an introductory video on area geology. The Special Exhibit Room hosts prominent precious metal and invited displays. The main gallery also showcases historic mining murals by Irwin Hoffman.

The basement contains numerous exhibits regarding radioactivity, fossils, basic geology, gemstones, meteorites, ultraviolet minerals and underground mining illumination. The outdoor geologic trail features seven outcrops with various geologic and paleontological points of interest, including fossilized dinosaur tracks, logs and leaves.

The Mines Geology Museum Gift Shop is on the lower level of the building. The shop features surplus mineral specimens, lapidary materials and equipment, fossils, books, fluorescent minerals, starter kits and related materials. Specimens range from “starter” pieces for less than $1, to fine specimens for the advanced collector.

Identification of specimens is performed between 10 a.m. and noon, Tuesdays and Thursdays.
