Our mission is to access, develop, and maintain exhibits and collections pertaining to mining and geology in Idaho, and to use the museum and its contents to promote education and understanding of mining, geology, and the related earth sciences.

The Idaho Museum of Mining and Geology (IMMG) was founded as a non-profit in 1989 and opened in the Trusty Dorm at the Old Idaho State Penitentiary in 1994. Since then we have shared Idaho mining stories and given countless visitors a peek into the fascinating study of earth sciences with an emphasis in Idaho geology. The 2300 sq.ft. museum includes a historic mining camp, lode and placer mining equipment, a historic mining elevator, a hand-held microscope, rocks and minerals from Idaho, fluorescent mineral display, meteorites, fossil display, and seismograph!
