[Illustration: FIG. 1.--Petroglyphs at Oakley Springs, Arizona.]
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.
From information received from Mr. Alphonse Pinart, pictographic records exist in the hills east of San Bernardino, somewhat resembling those at Tule River in the southern spurs of the Sierra Nevada, Kern County.
These pictographic records are found at various localities along the hill tops, but to what distance is not positively known.
In the range of mountains forming the northeastern boundary of Owen Valley are extensive groups of petroglyphs, apparently dissimilar to those found west of the Sierra Nevada. Dr. Oscar Loew also mentions a singular inscription on basaltic rocks in Black Lake Valley, about 4 miles southwest of the town of Benton, Mono County. This is scratched in the basalt surface with some sharp instrument and is evidently of great age. (Ann. Report upon the Geog. Surveys west of the 100th meridian. Being Appendix J J, Ann. Report of Chief of Engineers for 1876. Plate facing p. 326.)
Dr. W. J. Hoffman, of the Bureau of Ethnology, reports the occurrence of a number of series of etchings scattered at intervals for over twenty miles in Owen’s Valley, California. Some of these records were hastily examined by him in 1871, but it was not until the autumn of 1884 that a thorough examination of them was made, when measurements, drawings, etc., were obtained for study and comparison. The country is generally of a sandy, desert, character, devoid of vegetation and water. The occasional bowlders and croppings of rock consist of vesicular basalt, upon the smooth vertical faces of which occur innumerable characters different from any hitherto reported from California, but bearing marked similarity to some figures found in the country now occupied by the Moki and Zuñi, in New Mexico and Arizona, respectively.
