The National Park Service managed to acquire the property in 1965, and excavations were started soon after. The excavations revealed remnants of structural materials, specifically burned daub, a type of mud plaster. Burned daub was used in building construction at the time the mound was built, so its presence indicates that a building was present on top of the mound, likely a temple or the house of a chief.
Before the National Park Service acquired the property, it was used as agricultural land by modern day farmers. Some of the farmers actually lowered the mound to make it more suitable for farming. The plowing of the field and the mound area lowered the height of the mound significantly from its original 8 feet. When the National Park Service got the property of the mound and village site, the site was so reduced in height that it had to be repaired. After the excavations of the site were completed, the mound was rebuilt to what is presumed to have been its original height of eight feet. Today the mound dimensions are 8 feet in height by 85 feet across the base of the mound.
