This National Monument is located on the Alpine Scenic Loop in American Fork Canyon. The cave system is well known for its colorful formations, unique helictites, fault-controlled passages, alpine surroundings, and rich history.
The man-made cave system joins three natural caves that contain at least 42 types of cave formations-an unusually large variety. The uniquely colored cave features include unusual combinations of delicate helictites and anthodites in quantities not found in other caves worldwide.
The cave is open from mid-May to mid-October.
