A study of some projectile points collected in the region of Oaxaca, Mexico, was recently concluded. It was possible to relate most of the specimens to the typology employed at nearby Tehuacan. The earliest points date from the El Riego phase, beginning ca. 6800 B.C. Limited evidence suggests that, possibly because of pluvial conditions, the early folk of Oaxaca kept to the foothills rather than the valley floors. This may have effected cultural differences with Tehuacan. Oaxaca may also have had an important part to play in the migration of early man to South America.
