Find your own treasures at the Tulip City Gem and Mineral Club’s annual rock, mineral and jewelry show. At the show, visitors will have the opportunity to crack their own geode to find crystals. This is in keeping with this year’s theme “Geodes — Hidden Treasure.”
The A.E. Seaman Mineral Museum at Michigan Technological University in Houghton is loaning its display, “How Geodes Are Made.” It will include 10 museum-quality geodes from Mexico, Indiana, Illinois, Missouri, Kentucky and Argentina.
