Elephant Rocks State Park is a state-owned geologic reserve and public recreation area encompassing an outcropping of Precambrian granite in the Saint Francois Mountains in the U.S. state of Missouri. The state park is named for a string of large granite boulders which resemble a train of pink circus elephants. The park was created following the donation of the land to the state in 1967 by geologist Dr. John Stafford Brown. The park is used for picnicking, rock climbing, and trail exploration. It is managed by the Missouri Department of Natural Resources.
