San Pedro

The final chronological period of the Cochise culture in the Atacama region of northern Chile, contemporaneous with Tiahuanaco in Bolivia, c 500-1000 AD. Polychrome kero or beaker-shaped vessels are found in graves and typically, tool assemblages contain seed-grinding tools such as manos and metates, mortars and pestles, and a variety of projectile points, including the narrow stemmed, side-notched type which first appeared during Chiricahua. Pit houses (houses of poles and earth built over pits) are also characteristic. During the San Pedro stage, pottery appeared in the area of the Mogollon Indians. The Cochise tradition may be taken as the base for subsequent cultural developments among various Indians in the Southwest.

Most recent of the chronological periods of the Cochise culture. Typically, tool assemblages contain seed-grinding tools such as manos and metates, and a variety of projectile points, including the narrow stemmed, side-notched type which first appeared during Chiricahua. Sites generally became larger and more numerous during this period and the increasing appearance of simple pit houses is in keeping with the general trend to settled village life.
