Blake de Pastino, of Western Digs, has written an exciting article about a recent confirmation of the presence of a ceremonial road in the center of Cahokia, an ancient city in Illinois which was inhabited from AD 700-1400.
"While the existence of such a road had been the subject of debate and conjecture since the 1920's, the excavations finally confirm its presence, potentially changing our understanding of the Mississippian metropolis, said Dr. Sarah Baires of the University of Illinois."
