The Indiana Geological and Water Survey has partnered with the Indiana Department of Natural Resources to provide visitor guides for popular Indiana State Parks. Each guide includes the geologic story of the park and an updated trail map. They are sized for legal (8.5 x 14 inch) paper.

Please remember, fossil and rock collection is illegal in state parks. Take nothing but photographs, leave nothing but footprints!
