In addition to the unworked shells there are body and rim sherds from
at least two pottery vessels which came from a shell midden on the bay.
There is a single rim sherd (139614a) which comes from a shallow bowl
with a direct flat-topped rim. Color of both the interior and exterior
surfaces is buff. The paste is fairly coarse, with a granitic sand
temper which has also some pumice inclusions. There is also evidence of
vegetable-fiber inclusions. There is no mica in the paste. The fragment
is 5 mm. thick.
The second fragment (139614b) is a large rim and body sherd from a large
bowl which would have been 27 cm. in diameter and 17 cm. high. The rim
is direct, with a grooved lip (pl. 18, _a_, _b_). The surface color is
black to dark gray. The paste is coarse, with sand and quartz
inclusions, some of which are as large as 5 mm. in diameter. No mica is
present. The surface is scarred by burned-away vegetable inclusions. The
specimen is about 9 mm. thick.
This pottery could have been native-made pottery from the Mission
period, or it could have been derived from pottery-making Indians to
the north. Neither source has been adequately studied on the peninsula.
Comparable pieces have been seen, however, from mission ruins in central
and northern Baja California.
