Fragments of points.—Only two additional point fragments were recovered, neither of which are typable.
GROUND OR PECKED STONE
Ground or pecked stone, like that of chipped material, evidences a certain amount of continuity as compared to the Tank Site, but also changes slightly. The number of examples and types is considerably less, perhaps due in part to the proportional amount of digging done, though it is difficult to determine, as the Tank Site might well be classed as unusual in regard to its great quantity of implements. Where manos and metates were of frequent occurrence in the Tank Site, they become rare here. Though only two mortars and four pestles were found, it would indicate a considerable statistical increase over the Tank Site, especially when the amount of digging done in the two sites is compared. Slate pendants carry through as do stone disks. No cog stones were recovered though they appear to be an associate of the disks.
Metates
A slight shift may be noted in the types of metates. The shallow basin and the slab take precidence over the deep basin. As to material and form, no differences could be noted. The specimens from this site were not weathered so badly nor was the inverted position common. The number of each type recovered was as follows: shallow basin, 17; slab, 3; deep basin, 2; and 19 unidentifiable fragments.
Manos
Manos, like metates, were not too numerous nor varied in form. The finished specimens lack the perfection of the better made examples in the Tank Site. Considering the entire grinding complex, it is evident that the role played here was of less importance. This might be interpreted as indicative of a slight shift in the food economy. It is difficult to offer an explanation as to the direction or nature of such a shift, though there is some evidence suggesting greater emphasis was placed on hunting. By types, the following number of each was found: 4 mono-facial type IA; 20 bifacial type IIB; 3 wedge-shaped type IIC; and 1 type III, with three worked faces.
The ratio of manos to metates is quite different here than at the Tank Site. Here the ratio is 1.5 metates to 1 mano. Little explanation can be offered to this reverse trend other than it represents a breakdown of an older pattern as a result of a shift toward the mortar-pestle complex.
Mortars
The evidence for mortars rests upon two incomplete specimens. A single rim fragment, composed of a fairly course sandstone, resembles the Tank Site specimen, but having a somewhat larger diameter (about 10 inches). The second specimen is too fragmentary to allow any reconstruction of size.
