Spectral Stone will be at GeoFest 2026 at the Indiana State Museum this weekend. February 20th through 22nd, 10am to 5 pm.
From fossil fiends to crystal connoisseurs, there’s something for everyone at GEOfest!
Browse three floors and nearly 30 booths of vendors from across the country, selling a variety of items like beautiful gems, dazzling jewelry, giant geodes, incredible fossil and mineral specimens and more. With activities throughout the museum, children will enjoy digging into Indiana’s Ice Age past and testing their construction skills at the earthquake simulator. As part of the year-long celebration of America’s 250th birthday, you can discover more about Indiana’s geological history and learn which past U.S. presidents were fascinated with fossils. Walk through our galleries and the R.B. Annis Naturalist’s Lab to get a closer look at sparkling geodes, ancient fossils and geological artifacts.
Meet our friends from Irving Materials, Inc., who will have their cement truck here and help you make your own trilobite paperweight. You can also chat with the museum’s paleontologist and connect with several local science clubs and other community partners to learn more about earth sciences.
