The Junction Group is a site of earthworks located two miles southwest of Chillicothe, Ohio in the United States. The earthworks are associated with the Hopewell tradition.[1] The site has been described as "unusual" by contemporary archaeologists. Excavations in the early 19th-century state that the site was not for fortification, but was used for religious purposes, including for burials.
The group of mounds and enclosures is located alongside Paint Creek.[2] Today, most of the mounds and earthworks have been destroyed due to cultivation. Aerial photography has displayed cropmarks of the works. It has been noted that corn plants grow differently in the spots where the earthworks once stood.[3]
