Mines Museum of Earth Science in Golden (free)

The Mines Museum of Earth Science on the Colorado School of Mines campus is free to walk through every day from 10 a.m. to 4 p.m. The collection covers minerals, fossils, meteorites and Colorado mining history, and it pairs naturally with a Golden day: the farmers market, Clear Creek and the Colorado Railroad Museum are all minutes away.

Self-guided visits are always free. Guided 60-minute tours for groups of 4 to 15 cost $5 per child, $13 per adult and $7 per senior, and must be confirmed with staff at least a week ahead through museumevents@mines.edu. There is also a downloadable audio guide and printed brochure for the outdoor Bob Weimer Geology Trail. Closed Thanksgiving, Dec. 24-26, Dec. 31, Jan. 1 and July 4. Phone 303-273-3815.

Lesson hooks

  • Earth science: rock types, crystal structures, how meteorites are identified.
  • Colorado history: gold and silver mining and the towns it built.
  • Outdoors: the geology trail turns the campus into a field lab.
