This Middle Woodland Mound Site has been dated to approximately 2,200 years ago and is the oldest documented man-made site in Union County. Smithsonian archaeologists excavated the site in the middle 1880s, creating the map (below) and took hundreds of objects for its permanent collection. A selection of those objects is on loan from the Smithsonian to the Union County Heritage Museum and are currently on exhibit. Annual events are held for students and adults at the 63 acre Mound site that is owned by the Archaeological Conservancy. For tours and information contact the museum. The site opens at dawn and closes at dusk.
