Description
Preservation
Ancient Monuments of the Mississippi Valley fascinated many across the country, including Frederic Ward Putnam of the Peabody Museum of Archaeology and Ethnology at Harvard University. Putnam spent much of his career lecturing and publishing on the Ohio mounds, specifically the Serpent Mound. When he visited the Midwest in 1885, he found that plowing and development were dest…
Origin and chronology
In previous years, the civilization responsible for the creation of the Serpent Mound had been highly disputed amongst archaeologists, as can be seen in the material published in 2002. Its construction was often attributed to different civilizations. Very little additional evidence, such as artifacts and burials, can be found at the site of the mound, leaving it hard for archaeologists to trace its construction back to one civilization. Archaeologists generally acknowledged that the A…
Prehistory of Ohio
Several groups of Paleo-Indians (13000 B.C. to 7000 B.C.) occupied the land in Ohio prior to the Adena and Hopewell cultures. Evidence shows that numerous civilizations of Paleo-Indians occupied the land in Ohio, thriving through hunter-gatherer techniques, and ranged throughout the land. The Paleo-Indians hunted large game such as mastodon. Archaeologists have found remains of more 15…
Civilizations of the Midwest
The Adena culture consists of the pre-contact American Indian culture that lived throughout the midwest in states such as Kentucky, Indiana, Pennsylvania, West Virginia and most predominantly Ohio. The majority of these civilizations inhabited the Scioto River and Hocking Valleys in southern Ohio, as well as the Kanawha Valley near Charleston, West Virginia. This period is often referred t…
