Our annual rock show is a great time for the whole family! Rain or shine, we combined our event with the Halloween holiday when our show dates had to change - because what is a better skeleton than a fossil? We have trick-or-treating stations and even some of our vendors are joining in and crafts and games for the kids as well as exhibits and demonstrations. Fossils, Gemstones, Minerals, Crystals, Jade, Gold, Opals, Meteorites, Rough Rock, Slabs, Specimens, Art, Jewelry, Cathedrals, Food, Raffle, and more! All proceeds go to support the Sacramento Mineral Society, a 501(c)3 established in 1936 to help keep our doors open to continue to be a resource for our members and the Sacramento community.
