The Adena culture was a Native American collective that flourished between 800 B. C.-100 C.E. They constructed earthen mounds across Ohio, including this one known today as Ranger Station Mound. Although the Adena were Ohio's first agriculturalists and potters, they are especially renowned for their iconic earthworks. Archeologists believe these mounds were ceremonial centers where tribal members performed rituals and buried leaders. Many earthworks on prime agricultural land were later plowed by European settlers. To preserve what remained of the Zaleski Mound Group, the State Historic Preservation Office placed the Ranger Station Mound on the National Register of Historic Places in 1974. Today, the remaining Adena earthworks provide a unique window into Ohio's distant past.
