Note XI-36 — Chapter XI · ANTIQUITIES OF ARIZONA AND NEW MEXICO.

A writer in the N. Y. Tribune,—see Hist. Mag., vol. x., suppl., p. 95—describes a pyramid on the Colorado River, without giving the locality. It is 104 feet square, 20 feet high, and has at present a summit platform. It seems, however, to have been originally pointed, judging from the débris. The material is hewn stone in blocks from 18 to 36 inches thick, those of the outer facing being out at an angle. This report is perhaps founded on some of the ruins on the Colorado Chiquito yet to be mentioned, or quite as probably it has no foundation whatever. 'Upon the lower part of the Rio Colorado no traces of permanent dwellings have been discovered.' Whipple, Ewbank, and Turner, in Pac. R. R. Rept., vol. iii., p. 15. Arizona miners occasionally refer to the ruins of old Indian buildings on the Colorado, 40 miles above La Paz, on the eastern side, similar in character to those of the Gila. On Ehrenberg's Map of Arizona, 1858, they are so located, and that is all that is known of them. San Francisco Evening Bulletin, July 14, 1864.
