Boyd Mounds - This Native American mound site was constructed during the late Woodland -- early Mississippian period, from 800-1100 A.D. Archeologists tell us that there was a house here sometime around 500 A.D. and that the pottery found in the mounds was made before 700 A.D. Likely, the population was continuous over centuries with customs being handed down from generation to generation. Photo by Kathy Weiser-Alexander.
