On the north wall of Canyon de Chelly, one-fourth of a mile east of its mouth, are several groups of petroglyphs, consisting chiefly of various grotesque forms of the human figure, and also numbers of animals, circles, etc. A few of them are painted black, the greater portion consisting of rather shallow lines, which are in some places considerably weathered. Further up the canyon, in the vicinity of the cliff dwellings, are numerous small groups of pictographic characters, consisting of men and animals, waving or zigzag lines, and other odd figures. Lieut. James H. Simpson (_a_), in his Journal of a Military Reconnoissance, etc., presents a number of plates bearing copies of inscriptions on rocks in the northwestern part of New Mexico, among which are those on the so-called “Inscription rock” at El Moro, here reproduced as Fig. 57. The petroglyphs are selected from the south face of the rock. Lieut. Simpson states that most of the characters are no higher than a man’s head, and that some of them are undoubtedly of Indian origin. [Illustration: FIG. 57.--Inscription rock, New Mexico.] Among the many colored etchings and paintings on rock discovered by the Pacific railroad expedition in 1853-’54, Lieut. Whipple (_c_) notes those at Rocky dell creek, New Mexico, which were found between the edge of the Llano Estacado and the Canadian river. The stream flows through a gorge, upon one side of which a shelving sandstone rock forms a sort of cave. The roof is covered with paintings, some evidently ancient, and beneath are innumerable carvings of footprints, animals, and symmetrical lines. He also remarks (_d_) that figures cut upon a rock at Arch spring, near Zuñi, present some faint similarity to those at Rocky dell creek. Near Ojo Pescado, in the vicinity of the ruins, are petroglyphs, also reported by Lieut. Whipple (_d_), which are very much weather-worn and have “no trace of a modern hand about them.” Mr. Edwin A. Hill, of Indianapolis, in a letter, notes petroglyphs on the Denver and Rio Grande railroad, between Antonite and Espanola. Below Tres Piedras and near Espanola are rude sculptures, lining the valley on both sides of the road for a long distance, at least several miles. The canyon has a slope of about 45° and contains many bowlders, and on every available face pictographs are cut. Figures of arrows, hatchets, circles, triangles, bows, spears, turtles, etc., are outlined as if with some cutting-tool. The country had two years before been occupied by Apaches, but far greater age is attributed to the petroglyphs. Other petroglyphs actually within the geographical area of New Mexico are so near the border that they are treated of in connection with those of Colorado.
