A must-see. This large and complex site on the edge of Maçon Ridge once may have contained as many as 13 mounds. Two large mounds (Md. B and Md. D) are clearly visible from the marker. Another very low mound (Md. C) is nearby, but it’s more difficult to recognize. Three other possible mounds are to the east; seven possible mounds to the west were leveled before their status could be determined. The largest mound (Md. B) appears to be conical and measures about 20 feet tall, although about 5 feet of mound fill has been removed from its top. It’s almost 300 by 215 feet at the base. Soil sediments indicate it was built in a single stage. The other large mound (Md. D) was also built in one stage; it’s a platform mound, almost 11 feet tall and about 165 by 135 feet at the base. Although the site was occupied as early as the Poverty Point period (1700–1000 BC), radiocarbon dating of charcoal from beneath Md. B and Md. D shows the mounds date to the Coles Creek period (AD 700–1200).
