The Elephant Rocks are massive limestone formations sitting in a sea of grass on private farmland. The rocks were once sand at the bottom of the sea that accumulated 25 million years ago. These sediments were buried and the pressure turned the sand into rock, or limestone. When the whole area of limestone lifted and surfaced, the forces of the wind and water did their part in shaping the limestone.
