sided, blunt basal stem. A slight amount of basal thinning was at- 

 tempted and the chipping scars are not long but rather short. Chip- 

 ping was performed by transverse pressure terminating along a low 

 median line giving the projectile a lenticulate cross section. Second- 

 ary chipping along the edges border on the minute in size, giving the 

 blade an even, keen cutting edge. In overall dimensions, it measures 

 58 mm. in length, 20 mm. in maximiun width — which occurs about 

 midway down the object — and 8 mm. in maximum thickness — which 

 occurs about one-third the distance from the butt to the point. There 

 is a certain amomit of decomposition of the stone on both faces and 

 more so toward the lower half of the blade. 



Another rhyolite form from this same site resembles, somewhat, in 

 shape the tip of a 16th-century metal halberd pike head. This is a 

 long, 69-mm., narrow, parallel-sided blade terminating in a short, 

 blunt tip formed by bringing the parallel edges to a quick stubby 

 point. On either side of the stem are prominent shoulder barbs almost 

 at right angles to the stem. Since there is only a rudimentary portion 

 of the stem present, the true form the original assumed cannot be 

 determined. This point has a number of early characteristics, namely : 

 the stubby tip, parallel sides, and the various methods of chipping. 

 These same characteristics also occur in the Clovis, Folsom, and the 

 many Yuman forms. The anomaly is the presence of shoulder barbs 

 and an undeterminable stem. This blade appears to have been 

 initially fashioned by percussion and later both pressure chipping and 

 rapping were used in the completion of the object. The stubby tip 

 and the parallel edges, which are fairly even and straight, were sub- 

 sequently subjected to very fine retouching. 



A fairly large superficially triangular chert blade, side-notched, 

 serrated, and beveled on the left side when the blade is held with the 

 tip uppermost, is present in the collection. It is the only beveled 

 blade recovered from the entire reservoir basin and hence it is unique. 

 The blade was chipped into shape by using broad, shallow flakes 

 making the surface practically flat and of uniform thickness. The 

 beveled surface measures 4 mm. in height and was formed by pressure 

 chipping at the same time that the edge was serrated. A certain 

 amount of basal thinning is manifested in a number of parallel flakes, 

 which does not reach beyond the shoulder. This particular blade is 

 66 mm. long, 24 mm. across from one shoulder to the other, and the 

 basal width probably measures slightly over 25 mm. when complete. 

 A thickness of 5 mm. is uniform throughout. 



The side notches, 7 mm. wide and 3 mm. deep, are more than twice as 

 wide as they are deep. They are carefully thinned, showing no evi- 

 dence of retouching, and create definite shoulder barbs below a straight 

 base.
