The Law site originally consisted of three earthen mounds. Mound A, the largest of the mounds and the one to survive, is just under 20 feet tall and has a ramp facing south toward a plaza area. Mound B was originally 13 feet tall and was located southwest of Mound A. Mound C was located on the eastern edge of the plaza and has long since been plowed away. Its original dimensions are unknown. The mounds were built during the Mississippi Period (AD 1200-1600), though Native Americans may have been living here as early as AD 1000.
