The Hopewell tradition, also called the Hopewell culture and Hopewellian exchange, describes a network of precontact Native American cultures that flourished in settlements along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period.

Fort Ancient is a Native American earthworks complex located in Washington Township, Warren County, Ohio, along the eastern shore of the Little Miami River about seven miles (11 km) southeast of Lebanon on State Route 350. The site is the largest prehistoric hilltop enclosure in the United States with three and one-half miles (18,000 ft) of walls in a 100-acre (0.40 km2) complex. Built by the Hopewell culture, who lived in the area from the 200 BC to AD 400, the site is situated on a wooded bluff 270 feet (82 m) above the Little Miami. It is the namesake of a culture known as Fort Ancient who lived near the complex long after it was constructed.
The Adena culture was a Pre-Columbian Native American culture that existed from 500 BCE to 100 CE, in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex and ceremonial system.

Ancient Monuments of the Mississippi Valley (1848) by the Americans Ephraim George Squier and Edwin Hamilton Davis is a landmark in American scientific research, the study of the prehistoric indigenous mound builders of North America, and the early development of archaeology as a scientific discipline. Published in 1848, it was the Smithsonian Institution's first publication and the first volume in its Contributions to Knowledge series. The book had 306 pages, 48 lithographed maps and plates, and 207 wood engravings. The book was reissued in 1998 in paperback, with an introduction by David J. Meltzer, professor of anthropology at Southern Methodist University.
The Newark Earthworks in Newark and Heath, Ohio, consist of three sections of preserved earthworks: the Great Circle Earthworks, the Octagon Earthworks, and the Wright Earthworks. This complex, built by the Hopewell culture between 100 BCE and 400 CE, contains the largest earthen enclosures in the world, and was about 3,000 acres in total extent. Less than 10 percent of the total site has been preserved since European-American settlement; this area contains a total of 206 acres (83 ha). Newark's Octagon and Great Circle Earthworks are managed by the Ohio History Connection. A designated National Historic Landmark, in 2006 the Newark Earthworks was also designated as the "official prehistoric monument of the State of Ohio."
