The site is a detached portion of the Hopewell Culture National Historic Park, along with the Mound City Group, Hopewell Mound Group, Seip Earthworks, Spruce Hill Earthworks, and the High Bank Works.

[citation needed] Ephraim George Squier and Edwin Hamilton Davis visited the site in 1846.

There is a rectangle shaped work "with an attached circle, the latter extending into the former, instead of being connected with it in the usual manner."

Squier and Davis were impressed by the size of the walls, stating that "they resemble the heavy grading of a railway, and are broad enough, on the top, to admit the passage of a coach."

[3] Squier and Davis surveyed that parallel walls traveled from the northwestern corner of the rectangle to the river it the southwest.

No large mounds were found at the time of excavation, but two small oval shaped elevations were discovered.
