The party under Lieutenant Whipple (see Rep. Pac. R. R. Exped., III, 1856, Pt. III, p. 42) also discovered pictographs at Yampais Spring, Williams River. “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 traces of considerable artistic workmanship. Some observed by Dr. W. J. Hoffman, in 1871, were rather elaborate and represented figures of the sun, human beings in various styles approaching the grotesque, and other characters not yet understood. All of those observed were made by pecking the surface of basalt with a harder variety of stone.

Mr. G. K. Gilbert discovered etchings at Oakley Spring, eastern Arizona, in 1878, relative to which he remarks that an Oraibi chief explained them to him and said that the “Mokis make excursions to a locality in the cañon of the Colorado Chiquito to get salt. On their return they stop at Oakley Spring and each Indian makes a picture on the rock. Each Indian draws his crest or totem, the symbol of his gens [(?)]. He draws it once, and once only, at each visit.” Mr. Gilbert adds, further, that “there are probably some exceptions to this, but the etchings show its general truth. There are a great many repetitions of the same sign, and from two to ten will often appear in a row. In several instances I saw the end drawings of a row quite fresh while the others were not so. Much of the work seems to have been performed by pounding with a hard point, but a few pictures are scratched on. Many drawings are weather-worn beyond recognition, and others are so fresh that the dust left by the tool has not been washed away by rain. Oakley Spring is at the base of the Vermillion Cliff, and the etchings are on fallen blocks of sandstone, a homogeneous, massive, soft sandstone. Tubi, the Oraibi chief above referred to, says his totem is the rain cloud but it will be made no more as he is the last survivor of the gens.”

A group of the Oakley Spring etchings of which Figure 1 is a copy, measures six feet in length and four feet in height. Interpretations of many of the separated characters of Figure 1 are presented on page [46] et seq., also in Figures 156 et seq., page [237].

Mr. Gilbert 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. “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 etchings 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 etchings on the rocks in Cañon Segy, and in Keam’s Cañon, northeastern Arizona. Some forms occurring at the latter locality are found also upon Moki pottery.
