Arledge Mounds I and II

The Arledge Mounds are a pair of Native American mounds in the south central part of the U.S. state of Ohio. Located near Circleville in Pickaway County, the two mounds lie in the middle of a farm field, far from any roads. These two mounds are disparate in size: while the smaller mound's height is 5 feet (1.5 m), the other's is 20 feet (6.1 m), and their diameters are approximately 65 feet (20 m) and 120 feet (37 m) respectively.^[3]:1140
