McCormick's Creek: Indiana's First State Park (GM-21)
A mile-long canyon cut 100 feet into limestone, a scenic waterfall, and a quarry from which came some stone for the State Capitol are among the attractions of Indiana's oldest state park. Other notable geologic features, typical of limestone terrain, include large sinkholes, natural bridges, and small caves.

The limestone deposits, product of warm clear seas of 300 million years ago, include the Salem Limestone, a premier building stone of the world. This stone, made up of cemented small fossils and wave-broken shell fragments, is quarried in Monroe and Lawrence Counties.

The canyon was formed perhaps 50,000 years ago during the latest Ice Age when the climate was much wetter and colder than it is now. On a visit to McCormick's Creek State Park, take time to reflect on the geologic history and the forces that helped shape this part of Indiana.
