State Memorial Adena Mound

Miamisburg, Ohio * Montgomery County

On the high east bluff overlooking the Great Miami River

The Ohio Historical Society Marker at the foot of the mound
next to the steps says:

Miamisburg Mound, the largest conical earthwork in Ohio, originally was sixty-eight feet high with a diameter of three hundred feet. One excavating attempt in 1869 reduced the height to its present sixty-five feet. The mound was then partially investigated by means of a vertical shaft which extended from the top to the the base and connected with two horizontal tunnels. The exploration revealed one burial eight feet from the top containing a bark-covered skeleton and a vault twenty-eight feet lower that was surrounded by logs but without a burial. Along the sides of the vertical shaft were found various layers of sand and stones implying that the mound was built in several stages. The entire construction, however, has never been systematically excavated.

The conical shape, the types of burials, and the absence of associated earthworks indicate that the Miamisburg Mound was the work of Adena Indians, a prehistoric group that lived in the Ohio Valley between 1000 B.C. and 400 A.D. these peoples were the first in this area to domesticate plants for food, to settle in fairly permanent villages, and to make pottery. An important part of their way of life was the proper burial of the dead in graves that were covered with earth mounds, such as this one.

Another Adena mound comparable in size to the Miamisburg Mound is Grave Creek Mound. It is located in Moundsville, West Virginia.
