There were nine abraders, two of which are of particular interest. One
showed heavy use as an abrader on one side and three edges. Much of this
use was as a sharpener for small pointed objects. The other side, while
showing use as an abrader, was also cupped for grinding purposes. Over
much of the surface, powdered yellow ochre had become impregnated into
the porous sandstone. Another specimen showed long wide grooves on two
surfaces while another had been ground flat. This portion of the stone
was heavily impregnated with red ochre. The other abrading stones were
unmodified pieces except for the miscellaneous grooves resulting from
use (Fig. 24;1, top).
Four asymmetrical whetstones were found in the general midden. These
were about 5 × 8 cm. by 1.5 cm. One of these was bitted at one end much
like a celt. Their use as whetstones was rather obvious (Fig. 24;1,
bottom).
