282 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. Q3 



The two chipped points found in association with extinct bison near 

 Grand Island (Schultz, 1932) are suggestive of the Folsom type 

 (NAb4) but lack the fine retouching and complete longitudinal grooves 

 characteristic of typical Folsom points. They fit into the Signal Butte 

 series fairly well (NAb3) but have a partial, longitudinal groove 

 which is lacking on most of the Signal Butte I points of similar shape. 

 I am inclined to regard them as transitional between Signal Butte I 

 and Folsom. 



The Angus find (Figgins, 1931) is still too incompletely authenti- 

 cated to make cultural comparisons worth while. The scanty material 

 from the Cape site near Dalton, Nebr. (Bell and Van Royen, 1934, 

 p. 67), contains only one definite artifact type, a planoconvex, end 

 scraper with an unretouched back, which agrees closely with the pre- 

 dominant type of end scraper from both Signal Butte I and the Fol- 

 som culture (Lindenmeier site). It may well be significant that Bell 

 and Van Royen (1934, p. 69) tentatively suggest that the horizons 

 where these finds occur fit into the same periods of Sears' chronology 

 (1932, p. 621) that have been suggested for Signal Butte I. The two 

 large points ( NAb4) found in association with mammoth remains 

 near Dent, Colo. (Figgins, 1933). suggest knives or spears of the Fol- 

 som culture. Rather similar large leaf -shaped blades occur in Signal 

 Butte I (pi. 25, fig. I, g) but lack any longitudinal grooves and do not 

 seem to be as delicately retouched. The main characteristics of the 

 recently discovered I'olsom horizon near Fort Collins (Roberts, 1935) 

 have already been described, and the rather marked relationship be- 

 tween this culture and that of Signal Rutte I commented upon. No 

 definite geologic age has yet been assigned to either the Dent or the 

 Lindenmeier site, but they can probably be correlated either with the 

 ancient terrace system of the South Platte or with late Pleistocene 

 horizons in the Medicine Bow region of Wyoming. 



It is already certain that the human record in the Great Plains 

 extends far back into that still obscure period between the beginning 

 of the Recent and the close of the Pleistocene. Some believe that it 

 extends well into the latter period. The last 5 years have opened new 

 vistas in the human liistory of the region and there is no reason why 

 subsequent years should be less fruitful. 



CULTUR.\L AFFILL^TIONS WITH ADJACENT AREAS 



Considering the present status of archeological knowledge con- 

 cerning the States bordering Nebraska, it is obviously premature to 

 attempt any detailed cultural comparisons. Of South Dakota, Wyom- 

 ing, Colorado, Kansas, and Iowa, only the last has been at all clearly
