Adena Mound

AKA Knob Prairie Mound

The largest conical mound in Clark County, The Enon Adena Mound is the second largest in Ohio. Miamisburg Mound, the largest, is about 35 miles southwest of Enon.

Listed in the National Register of Historic Places, and owned by the Village of Enon, this mound has little verified published information. Located on what was called Knob Prairie Mound Farm, the mound was reportedly used by General George Rogers Clark in 1780 as a vantage point prior to the attack on the Shawnee Village of Picawey, located less than two miles to the north.

Although no reliable report exists as to any professional exploration of this mound or any Adena artificats or material obtained, there is a brief account of an alleged partial excavation reported in “Beer’s History of Clark County”. Reportedly the mound was opened around 1870-1880 by local young persons. An indentation on the northwest side of the mound and an irregular area where the dirt was thrown is very likely the result of this excavation.

It is reported there was top soil all the way down the center from the summit to a room of stone construction. The room was the shape of a tapered bake oven and high enough for a person to stand in. There was no mention of Adena artifacts or any material evidence found to indicate burials existed in the mound. Due to the lack of archeological training it is unlikely the young persons would have recognized evidence.

The Mound Farm, 84.64 acres, was purchased in 1952 from Paul Pence by Charles Beaver who developed the Indian Mound Estates and deeded the mound to the Village in 1953. The Enon Mound was the center of a large dirt race track during the early 1900’s. Here, not far from the dust of a dead civilization, thoroughbreds raced and won governor’s cups at state fairs. Evidence of the race track still exists on lot #7 on Meadow Lane.

The Mound encompasses over one acre and is 574 feet in circumference and 40 feet high. The estimated 12,800 cubic yards of top soil would require 2,133 trucks to move it. If the average person could carry about 35 pounds, and soil weighs about 100 pounds per cubic foot, then it would have taken about one million loads to carry the soil from the surrounding area.
