Effigy mound

Native American burial mound

An effigy mound is a raised pile of earth built in the shape of a stylized animal, symbol, religious figure, human, or other figure. The Effigy Moundbuilder culture is primarily associated with the years 550–1200 CE during the Late Woodland Period, although radiocarbon dating has placed the origin of certain mounds as far back as 320 BCE.
