OWENS VALLEY.
In the range of mountains forming the northwestern boundary of Owens valley are extensive groups of petroglyphs, apparently dissimilar to those found west of the Sierra Nevada. Dr. Hoffman, of the Bureau of Ethnology, hastily examined them in 1871 and more thoroughly in the autumn of 1884. They are now represented in Pls. I to XI. So large a space is given to these illustrations because of their intrinsic interest, and also because it is desirable to show for one locality what is true of some others, viz, the very large number of petroglyphs still to be found in groups and series. Even with the present illustrations, the petroglyphs in Owens valley are by no means exhaustively shown.
Dr. Hoffman’s report is as follows:
One of the most important series of groups is that in the northern portion of Owens valley, between the White mountains on the east and the Benton range on the west. On the western slope of the latter, at Watterson’s ranch, is a detached low butte or mesa, upon the blackened basaltic bowlders and cliffs of which are numerous deeply cut characters, the most interesting of which are reproduced in Pls. I and II. The illustrations are, approximately, one-twelfth real size. The designs of footprints, in the lower left-hand corner of Pl. I, vary in depth from half an inch to 1½ inches. They appear to have been pecked and finally worked down to a uniform and smooth surface by rubbing, as if with a piece of stone or with wood and sand.
In almost all, if not all, instances throughout the entire series referred to in this description the sculptured surfaces have assumed the same shining blackened luster as the original and undisturbed surface of the bowlder, caused by gradual oxidation of the iron present. This would seem to indicate considerable antiquity of the petroglyphs.
On the northeast angle of the mesa referred to were found the remains of an old camp, over which were scattered large quantities of arrowheads, knives, and flakes of obsidian. This in itself would be insignificant, but the fact that many of the specimens of this material have been lying exposed to the elements until the upper surface has undergone change in color, so as to become bleached and friable, in some instances to the depth of from one-tenth to one-fourth of an inch, warrants the inference that the relics may have been made by the same people who made the petroglyphs, as the worked relics generally differ from those of the present Indians by being larger and less elaborately finished.
At the lower end of the southeastern slope of the mesa are a number of flat rocks bearing mortar holes, which have no doubt been used in grinding grass seed and other grains.
