AN ABORIGINAL QUARTZITE QUARRY IN 

 EASTERN WYOMING. 



LOCATION AND RECENT HISTORY OF THE QUARRY. 



The quarry is situated near the central southern border of Con- 

 verse County and within a few miles of Laramie County. It is about 

 half way between the towns of Keeline on the Fremont, Elkhorn 

 and Missouri Valley Railroad and Glendo on the Union Pacific, Den- 

 ver and Gulf Railroad. It is not, however, accessible from either of 

 these stations. 



My attention was first directed to the quarry by Mr. E. S. Riggs 

 of the Geological department of the Field Columbian Museum. Mr. 

 Riggs, while on a paleontological expedition to Wyoming in 1895, 

 passed over a portion of the quarry and readily recognized its nature. 

 Mr. Walter C. Wyman, of Evanston, Illinois, also heard of the 

 quarry and in April of this year brought to the Museum a few speci- 

 mens which had been collected by Judge Eastman, of Chicago, in 

 company with Mr. Sidney Bartlett, of Cheyenne, in 1899. Mr. Bart- 

 lett had previously visited the quarry in 1893 and wrote a brief 

 account of it, which appeared in the San Francisco Examiner. Messrs. 

 Lauk and Stein, two ranchmen living in Whalen Canon, heard of the 

 quarry in 1882 from some cowboys and for a long time it was known 

 as the "Mexican mine." Indeed, so strong was the impression that 

 the quarry was an abandoned " Mexican mine," that Lauk and Stein 

 decided to investigate the matter, and in 1886 they made some exca- 

 vations in the vicinity and in 1891 they hired a man, who worked for 

 several weeks; it is, perhaps, needless to say that the results of these 

 investigations were not satisfactory to the ranchmen. 



THE ROUTE TO THE QUARRY. 



In May of this year, accompanied by Mr. Stewart Culin, I 

 reached the ranch of Lauk and Stein by using the railroad from 

 Cheyenne to Guernsey and by driving seven miles north from
