Since 1972. Rock hobbyists from all over the country will display their collections. It’s informal tailgate format offers a low cost venue for field collectors and local mineral/lapidary clubs to share their latest finds with children, teachers, rockhounds, and the general public. The show is held at Mesa Community College at Dobson Rd. and the Superstition Freeway in Mesa, AZ and parking and admission are free to the public. One goal of this show is to increase the interest of children in rocks, minerals, geology, and science. Children can become interested in science through minerals, crystals, and fossils, and our hope is to encourage their interest. Several groups will have free samples for children and for teachers and there are free activities as well.
