The upper characters in A on Pl. IV represent the trail of a grizzly bear--as indicated by the immense claws--followed by a human footprint. The original sculpturings are clearly cut, the toes of the man’s foot being cup-like, as if drilled with a blunt piece of wood and sand. The tracks average 15 inches in length and vary in depth from half an inch to more than an inch. The course of direction of the tracks, which are cut upon a horizontal surface, is from north-northeast to south-southwest. [Illustration: BUREAU OF ETHNOLOGY TENTH ANNUAL REPORT PL. IV PETROGLYPHS IN OWENS VALLEY, CALIFORNIA.] In E is the semblance of an apparently two-headed snake, as also in _a_ on Pl. VII. It is possible that this was pecked into the rock to record the finding of such an anomaly. The occurrence of double-headed serpents is not unique, five or six instances having been recorded, one of which is from California, and a specimen may be seen in the collection of the U. S. National Museum. In Pl. V, _c_, _e_, _g_ are characters resembling some from the Canary islands [see Figs. 144 and 145], as well as many of the cupstones and dumb-bell forms from Scotland [see Figs. 149 and 150]. [Illustration: BUREAU OF ETHNOLOGY TENTH ANNUAL REPORT PL. V PETROGLYPHS IN OWENS VALLEY, CALIFORNIA.] An interesting specimen is presented in _d_, on Pl. VI, resembling the Ojibwa thunder bird, as well as etchings of Innuit workmanship to denote man [as shown in Fig. 1159]. The figures presented in Pl. III are the northernmost of the series, of which those on Pl. VII form the southernmost examples, the distance between these two points being about 2 miles.

VII PETROGLYPHS IN OWENS VALLEY, CALIFORNIA.] For the space of 4 miles southward there are a few scattered petroglyphs, to which reference will be made below, and the greatest number of characters are not found until the southernmost extremity of the entire series is reached. These are over the surface of immense bowlders lying on the east side of the road where it passes through a little valley known locally as the Chalk grade, probably on account of the whitened appearance of the sand and of some of the embankments. A general view of the faces of the bowlders upon which the chief sculpturings occur is presented in Fig. 17. The petroglyphs are represented in Pls. VIII to XI.
