A stone mound believed to have been constructed by pre-historic Indians before Columbus discovered America. The mound is composed of a bird in flight with its head turned toward the east and wings outspread. It measures 102 feet from head to tail and 120 feet from wingtip to wingtip, while the body rises to about 10 feet above the surrounding surface. The mound is though to have been built for burial purposes.
