Colorado School of Mines Geology Museum The museum is at 1310 Maple St. (corner of 13th and Maple Streets) on the CSM campus, Golden, and is well worth a visit at any time; daily hours are 9-4 Mon. through Sat., 1-4 Sundays. The beautiful new museum at the Colorado School of Mines is one of the treasures of our state’s legacy. Filled with fabulous mineral, ore, and fossil specimens, the collection has been amassed since the earliest days of the Territorial School of Mines in the 1870s. "Did you know?", "Evaluation of specimens is performed between 10 a.m. and noon, Tuesdays through Thursdays." If you have a mystery rock/mineral specimen that has always puzzled you, considering bringing it to show them at these times.
