34 ANNUAL REPORT SMITHSONIAN INSTITUTION, 19 3 5 



Dr. Frank H. H. Roberts, Jr., archeologist, devoted considerable 

 time during the year to a study of the problem of so-called Folsom 

 man. Extensive correspondence was carried on with collectors 

 throughout the country concerning their finds of Folsom points and 

 many examples were sent to him for study, photographing, and 

 measuring. As a result of this work much new information was ob- 

 tained concerning variations in this peculiar type of projectile point 

 and its distribution. 



Dr. Roberts left Washington September 23, 1934, for Fort Collins, 

 Colo., to investigate a site which had been reported to the Smithso- 

 nian Institution by Maj. Roy G. Coffin, professor of geology in Colo- 

 rado State College. The site was discovered in 1924 by Judge C. C. 

 Coffin and his son, A. L. Coffin, of Fort Collins. Among the speci- 

 mens were points which later were identified as belonging to the 

 Folsom type, the oldest thus far known in North America. Dr. 

 Roberts spent 6 weeks exploring the site, with the permission of the 

 owner of the land, William Lindenmeier, Jr., of Fort Collins. From 

 an intact midden layer 14 feet below the present ground level, and a 

 quarter of a mile distant from the place of the original finds by the 

 Coffins, he procured a whole series of implements which definitely 

 establish a complex for the Folsom horizon. 



Dr. Roberts returned to Washington November 20, 1934, and dur- 

 ing the winter months prepared a manuscript detailing the results of 

 his work. This paper, entitled "A Folsom Complex: Preliminary 

 Report on Investigations at the Lindenmeier Site in Northern Colo- 

 rado ", was published June 20, 1935, in the Smithsonian Miscel- 

 laneous Collections, vol. 94, no. 4, publ. no. 3333. 



Dr. Roberts left Washington again for Fort Collins on May 26. A 

 camp was established at the Lindenmeier site and excavations on 

 a larger scale than those of the preceding autumn were begun. The 

 digging yielded numerous specimens of stone implements and a con- 

 siderable quantity of bison bones, indicating that they are from much 

 larger animals than the modern bison. A number of stone imple- 

 ments were found in dii*ect association with these bones, and one 

 vertebra contains the tip end from a typical Folsom point. 



While the work at the Lindenmeier site was progressing. Dr. 

 Roberts visited a number of locations in the northern Colorado area 

 where Folsom specimens have been found. None of the latter indi- 

 cated possibilities for increased knowledge on the subject comparable 

 to those at the Lindenmeier site. 



During the month spent in the office Dr. Roberts also worked on 

 manuscripts detailing the results of archeological work conducted 

 in Arizona and at Shiloh National Military Park, Tenn.
