occupied zone containing almost continuous concentrations of flint 

 and numerous bones, mostly of bison; a few stone artifacts, not in- 

 cluding points, also had been found. Very scanty material had been 

 uncovered in level 83. In 1950, two higher occupational zones, at 91 

 and 92 feet, and a suggestion of a zone just below 83, were uncovered. 

 Artifacts were rare or absent from those parts of all levels excavated 

 except 88, which yielded four points and point fragments and a num- 

 ber of other artifacts. In 195 1, an area of 925 square feet was exca- 

 vated to augment the information on the previously known cultural 

 levels and to expand the total number of known levels to seven. By 

 the end of this field season, the western and southern limits of the 

 site had been determined, but to the north and east the cultural 

 deposits extend beyond the boundaries of the investigated areas. 

 Again all levels except 88 yielded disappointingly scanty cultural in- 

 formation. Level 88, the major occupational horizon at the site, pro- 

 duced a considerable number of artifacts, including sufficient points 

 and fragments to bring the total found in this level to 27. With few 

 exceptions, these points correspond to the description of the Plain- 

 view type. They are predominantly parallel-sided, concave-based, 

 skillfully chipped, and exhibit basal grinding. Most of the exceptions 

 are Meserve points, as named by Davis, with sides constricted sharply 

 toward the tip and a blade which has a pronounced right-hand bevel. 

 Two points of this type have been reported from the vicinity of 

 Grand Island, Nebr., in association with Bison occidentalis. Among 

 the other artifacts from the level are a few thin, well-made blades 

 with straight bases which seem to constitute a type. 



Among the major accomplishments at this site during the two sea- 

 sons are the recovery in geological context of numerous Plainview 

 points, the definition of at least a limited accompanying stone artifact 

 inventory, and the establishment of the Plainview-Meserve associa- 

 tion. Archeologically, Level 88 at 25FT42 appears to correlate with 

 Zone R at site 25FT41, where Plainview points were found in a 

 deposit approximately 8 feet above Zone C, the occupants of which 

 made points of Scottsbluff type. 



Other activities of the Museum party in 1951 included the testing, 

 with largely negative results, of site 25FT51 in the spillway area at 

 the dam and the topographic mapping of the lower part of Lime Creek 

 valley and the adjacent section of Medicine Creek. Paleontological 

 and geological studies of the area were also continued, partly for the 

 purpose of illuminating the problems of dating the early sites dis- 

 cussed above. On the basis of these studies, the loess above Level 92 

 at 25FT42 "seems to have been deposited near the climax of and dur-
