Miamisburg Mound is one of the largest Adena burial mounds in North America.
Miamisburg Mound is one of the two largest conical mounds in eastern North America. The other is West Virginia's Grave Creek Mound. It is a burial mound built by the people that archaeologists have called the Adena culture (800 B.C. to 100 A.D.). Adena was the name Governor Thomas Worthington called his estate in Chillicothe, Ohio. It was at that estate that the first mound of this group of prehistoric Native Americans was excavated in 1901.
The Miamisburg Mound is 65 feet tall and 800 feet in circumference. It contains 54,000 cubic yards of earth, which corresponds to the contents of more than 3,400 dump trucks.
Excavations conducted in 1869 revealed details of construction suggesting the Adena culture built the mound in several stages. The excavators found a layer of flat stones, overlapping like shingles on a roof, at a depth of 24 feet below the surface. At one point in its history, the mound had a stone facing. Monuments like Miamisburg Mound served as cemeteries for several generations of ancient Ohioans. They also may have marked the boundaries of tribal territories.
Miamisburg Mound is listed on the National Register of Historic Places. It is located in the City of Miamisburg in Montgomery County, Ohio.
