Fish bones were present in some quantity, but were not as abundant 

 as might have been expected. The most common shellfish was 

 Aequipecten circularis, which constituted approximately one-half of the 

 total number. No mammal or bird bones were recovered. 



The most abimdant stone artifacts consisted of round polishing 

 stones, hammerstones and manos, or grinding stones, all adapted from 

 naturally shaped beach stones. One broken metate leg was found in 

 layer 0-12 inches. Three rather crude, blunt stone celts were found, 

 two in layer 0-12 inches, one in 12-24 inches. The manos were of no 

 standard shape, but generally short rather than long, and somewhat 

 flat in cross section. The polishing stones and hammerstones varied 

 in size from that of a golf ball to somewhat larger than a baseball. In 

 the 12-24 inch level was an interesting graver made from a lamellar 

 flake of yellow flint. 



Since the concentration of midden material seemed to increase 

 toward the northeast corner of trench 1 we laid out trench 2, 25X25 

 feet parallel to trench 1, and just to the northeast of it. Over a portion 

 of this area was a stone rectangle, 19 feet square, which lay on the 

 surface, possibly a house foundation. Some of the stones weighed 

 from 200 to 300 pounds each. 



In trench 2, the midden layer varied from 32 inches in thickness 

 along the west wall to 24 inches on the east wall. We carried the 

 excavation to an actual depth of 44 inches, finding the base material 

 to be the same as in trench 1. We could find no traces of a floor or 

 structure under the stone "foundation." 



In general, the contents of the midden were similar to those in 

 trench 1, but stone objects were somewhat more abundant. In the 0-12 

 inch level we found two legless metates; one rectangular, the other 

 oval. The latter had been worn so thin that a hole had formed in the 

 bottom. In this level was also a small but well polished celt with a 

 sharp cutting edge, a number of hammerstones and manos made from
