Hammerstones
Seven pebble hammerstones were found in the general excavations. Most of them were either sandstone or chert and of nondescript shape ranging in size from 4 to 8 cm. in diameter. Many of the sandstone specimens showed use as grinding Stones as well as hammerstones, again pointing up the multiple tool use of pebbles. The chert pieces were not shaped, showing only the natural weathered surfaces except where they had been used.
