The Pinal Geology & Mineral Museum
 opened in 2016 as the dream of founding director Dr Ray.Grant.

Located within the Artisan Village of Coolidge, Arizona, the Museum honors the mining, mineral, and geologic heritage of Arizona

The Museum features displays of Arizona rocks, minerals, and paleontology specimens. A collection of minerals from around the world, with a special emphasis on Australian minerals complements our material from Arizona.

Numerous people have provided their personal collections to the Museum as part of our base collection so visitors can view the gifts of the Earth, and not only the beauty of the natural world but become excited to pursue the earth sciences as a career or hobby.

For our younger visitors, we have several activities available, including a treasure hunt, fossil dig, and mineral dig. A small gift shop provides minerals and fossils to take home. We also have a small browsing library available to visitors, though items must remain in the Museum.

Please Donate Today!
