Did you know that buried beneath the rich Iowa soil are some of the best geodes in the world? That’s right; the area around Keokuk, Iowa, is known by rockhounds far and wide. And perched on the edge of what’s generally considered Iowa’s geode country (a 70-mile radius from Keokuk) is a quiet, beautiful lake bearing the name of this famous rock found near its shores.

Geode State Park is an Iowa state park that was founded in 1937. As you might have guessed, it’s named for the extra beautiful, extra high-quality geodes found in this area of Iowa.
