Indiana's Largest Hopewell Earthwork Was Utilized in the Path of Souls Rituals: Stellar alignments at the Winchester, Indiana Ancient Earthworks

Hopewell earthworks and mounds are among some of the most intriguing and mysterious geometric formations created in the ancient world. "Hopewell" refers to a Native American mound-building era that developed from the earlier Adena culture, with both names derived from excavated mound sites (on historic plantations). Adena and Hopewell spanned the approximate timeframe of 1500 BC to AD 900 and were gradually replaced by another mound culture called "Mississippian." See the newly issued Illustrated Encyclopedia of Native American Indian Mounds & Earthworks for background information.
