Rock out at the 17th annual GeoFest from Feb. 21-23, 2020! Browse a wide variety of fossils, cut and uncut gemstones, and minerals from all over the world. Purchase jewelry or crafts made from natural materials, and add one-of-a-kind specimens to your collection. Plus, enjoy family-friendly activities around the museum by helping our fossil zookeeper with "feeding time" and exploring Indiana's ancient seas through a scuba diving scavenger hunt. Make amethyst jewelry or a pet rock, then join the rock and roll race.
