DescriptionAs the name Medicine Rock indicates, these wind-weathered sandstone formations held spiritual and cultural significance to Native American tribes; the Siouan name for the rocks was Inyan-oka-la-ka, “Rock with a hole in it.” In 1883, Theodore Roosevelt described the Medicine Rocks, which he visited during a hunting trip, as “fantastically beautiful a place as I have ever seen.” In 1957, the Carter County commissioners donated 320 acres for a state park, which was officially created in 1965.
