"Beyond were towering mounds and vestiges, indicating the existence of a greater city than any we had yet encountered. In wandering among them Dr. Cabot and myself counted thirty-three, all of which had once held buildings aloft. The field was so open that they were all comparatively easy of access, but the mounds themselves were overgrown.
I clambered up them till the work became tiresome and unprofitable; they were all, as the Indians said, puras piedras, pure stones; no buildings were left; all had fallen; and though, perhaps, more than at any other place, happy that it was our fortune to wander among these crumbling memorials of a once powerful and mysterious people, we almost mourned that our lot had not been cast a century sooner, when, as we believed, all these edifices were entire."
(Stephens, vol. 2:127)
