_Side-notched points (pl. 23, g-h)._--These two specimens differ from
those of the Tank Site in that the base tends to be more concave rather
than convex. Only one of the Tank Site specimens showed a slight
concavity. These specimens differ somewhat from the side-notched concave
points that are typical of the protohistoric and historic period in that
they are broad across the base and proportionately short. Their lengths
are 3.5 and 2.5 cm.
_Contracting-stem points (pl. 23, f)._--This single specimen is larger
than those of the Tank Site and differs in that the sides tend to be
convex near the tip, concave at the mid-section and base, terminating in
well-defined tangs. Were it not for the well-defined tapering stem, the
basal portion would be concave. Typologically this type finds a good
parallel in D. B. Rogers' Hunting and Canalino specimens and a somewhat
lesser similarity to the Gypsum Cave material. (An extended discussion of
this type will be found in the conclusion.) Length, 7 cm.
_Convex-base points (pl. 23, m)._--This type is not represented in the
Tank Site series and is known here only through a single incomplete
specimen. It is a type not uncommon to the later coastal group.
Reconstructed length, 3.5 cm.
_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.
