Did you realize that one of the greatest treasures in the heart of the heartland is hiding right under our feet?

Coldwater Cave, Iowa’s longest and most spectacular cave, is located beneath the gently rolling hills of farm country in northeast Iowa. It is a living breathing wonder of nature.  This natural wonder has been studied and mapped since 1967.

Come and hear Ron and Nicolette Bonnstetter tell about their adventure in the cave. Ron and other students mapped several miles, finding an underwater fall that was 25 feet tall. There are photos so… you don’t have to duck or get wet to learn about this cave. Join us on this Zoom adventure, with Ron and Nicolette as our guides.
