Geometric Enclosure

This earthen geometric enclosure is 1200 feet in diameter and encloses 16.5 acres, with walls 5 feet high. Archaeologists have suggested that it defined sacred space where various rituals or ceremonies took place. It was not built on level ground, and the eastern wall is about 40 feet higher in elevation than the western wall. One hypothesis suggests that Native Americans built the embankment wall around this drainage system to create a water catchment.
