Those who have made careful studies of subsurface conditions 

 of Oklahoma are of the opinion that other buried ranges may occur 

 in various sections of the state, particularly in the Robberson field of 

 Garvin county, in the Cushing oil field, and in the Inola, Spavi- 

 nawr region of eastern Oklahoma. 



For many years we have known of an exposure of granite ^long 

 Spavinaw creek east of Grand river, in Mayes county. David Dale 

 Owen was the first geologist to mention this exposure. Drake, 

 Snider and others who studied the granite have been inclined to con- 

 sider it a dike, but it is now believed to be the summit of a buried 

 granite ridge now being slowly uncovered by erosion. 



XXVI. INDIAN PICT^OGRAPHS IN THE WICHITA 

 MOUNTAINS 

 By S. Weidman 



From the Oklahoma Geological Survey and Department of 

 Geology, University of Oklahoma. 

 "While investigating the problem of Pennsylvanian-Permian 

 glaciation in the Wichita mountains the writer, in September, 1922, 

 discovered some examples of Indian picture writii.g at the west 

 end of Camels Back mountain, located about eleven miles south- 

 west of Hobart The picture writing is engraved on the very 

 smooth or polished surface of granite exposed at the base of the 

 mountains, and it occupies a space some six feet in width by five 

 feet in height. The accompanying Figure 7 from a photograph 

 m.ade by G. W. Long, of Hobart, reveals the character of the 

 writing. 



The lines of engraving on the polished granite are variable 

 in distinctness, but they are usually about one-half to three-quarters 

 inches in width and one-sixteenth inch in depth. In order to secure 

 a good photograph of the writing the engraved lines on the granite 

 were marked with black crayon. Later the lines in the photograph 

 were retouched for the purpose of m.aking the half-tone engraving 

 shown in Figure 7. Although some obscure markings on the granite 

 are not brought out the main features of the pictographs are shown 

 in the figure. 



• So far as could be learned by the writer this example of 

 Indian writing was not known by the white men living in the region. 

 However, the Kiowa Indians knew of it. Since the finding of this 

 pictograph other examples have been reported to occur on smooth 

 granite surfaces in the Devils Canon, located some 10 miles west 

 of Camels Back. It is quite probable that further investigation
