Adena culture

The Adena culture was a Pre-Columbian Native American culture that existed from 1000 to 200 BC, 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. The Adena lived in an area including parts of present-day Ohio, Indiana, Wisconsin, West Virginia, Kentucky, New York, Pennsylvania and Maryland.

Adena sites are concentrated in a relatively small area - maybe 200 sites in the central Ohio Valley, with perhaps another 200 scattered throughout Wisconsin, Indiana, Kentucky, West Virginia and Pennsylvania, although they may once have numbered in the thousands. The importance of the Adena complex comes from its considerable influence on other contemporary and succeeding cultures. The Adena culture is seen as the precursor to the traditions of the Hopewell culture, which are sometimes thought as an elaboration, or zenith, of Adena traditions.

The Adena were notable for their agricultural practices, pottery, artistic works and extensive trading network, which supplied them with a variety of raw materials, ranging from copper from the Great Lakes to shells from the Gulf Coast. The Adena culture was named for the large mound on Thomas Worthington's early 19th-century estate called "Adena", in Chillicothe, Ohio.

Lasting traces of Adena culture are still seen in their substantial earthworks. At one point, Adena mounds numbered in the hundreds, but only a small number of Adena earthen monuments still survive today. These mounds generally ranged in size from 20 feet (6.1 m) to 300 feet (91 m) in diameter and served as burial structures, ceremonial sites, historical markers and possibly gathering places. These mounds were built using hundreds of thousands of baskets full of specially selected and graded earth. According to archaeological investigations, Adena mounds were usually built as part of burial ritual, in which the earth of the mound was piled immediately atop a burned mortuary building. These mortuary buildings were intended to keep and maintain the dead until their final burial was performed. Before the construction of the mounds, some utilitarian and grave goods would be placed on the floor of the structure, which was burned with the goods and honored dead within. The mound would then be constructed, and often a new mortuary structure would be placed atop the new mound. After a series of repetitions, mound/mortuary/mound/mortuary, a quite prominent earthwork would remain. In the later Adena period, circular ridges of unknown function were sometimes constructed around the burial mounds. Adena mounds stood in isolation from domestic living areas.
