Lieut. Col. Emory (a) reports that on a table-land near the Gila bend is a mound of granite bowlders, blackened by augite and covered with unknown characters, the work of human hands. On the ground near by were also traces of some of the figures, showing that some of the pictographs, at least, were the work of modern Indians. Others were of undoubted antiquity. He also reports in the same volume (b) that characters upon rocks of questionable antiquity occur on the Gila river at 32° 38′ 13″ N. lat. and 190° 7′ 30″ long. According to the plate, the figures are found upon bowlders and on the face of the cliff to the height of 30 feet.

Lieut. Whipple (a) remarks upon petroglyphs at Yampais spring, Williams river, as follows:

The spot is a secluded glen among the mountains. A high shelving rock forms a cave, within which is a pool of water and a crystal stream flowing from it. The lower surface of the rock is covered with pictographs. None of the devices seem to be of recent date.

Many of the country rocks lying on the Colorado plateau of northern Arizona, east of Peach springs, bear petroglyphs of considerable artistic workmanship. Some figures, observed by Dr. W. J. Hoffman in 1872, were rather elaborate and represented the sun, human beings in various styles approaching the grotesque, and other characters not understood. All of those observed were made by pecking the surface of basalt with a harder variety of stone.

Mr. Gilbert also obtained sketches of etchings in November, 1878, on Partridge creek, northern Arizona, at the point where the Beale wagon road comes to it from the east. He says: “The rock is cross-laminated Aubrey sandstone and the surfaces used are faces of the laminæ. All the work is done by blows with a sharp point. (Obsidian is abundant in the vicinity.) Some inscriptions are so fresh as to indicate that the locality is still resorted to. No Indians live in the immediate vicinity, but the region is a hunting ground of the Wallapais and Avasupais (Cosninos).”

Notwithstanding the occasional visits of the above named tribes, the characters submitted more nearly resemble those of other localities known to have been made by the Moki Pueblos.

Rock drawings are of frequent occurrence along the entire extent of the valley of the Rio Verde, from a short distance below Camp Verde to the Gila river.

Mr. Thomas V. Keam reports drawings on the rocks in Canyon Segy, and in Keam’s canyon, northeastern Arizona. Some forms occurring at the latter locality are found also upon Moki pottery.
