Although geodes of different kinds are found all over the world, the greatest abundance and variety are found in the outcropping of the Mississippian lower Keokuk bed within a 70 mile radius of the intersection of the Mississippi and Des Moines Rivers. Southeastern Iowa is one of the state’s best Geode collecting areas. Geode State Park in Henry County is named for the occurrence of the geode.
