Picnic areas, walking trails, rock gardens, gift shops, and a visitor center have all since been developed. In 1988, Cave of the Mounds was designated as a National Natural Landmark. In addition to cave tours, Cave of the Mounds now annually educates thousands of school children on field trips, welcomes scouts and other youth groups for educational programs and overnights, hosts public and private events throughout the year, and is home to Camp Brigham youth summer camps. Cave of the Mounds is celebrating 80 years since the cave was discovered in 1939.
