Excavations to investigate stratigraphy at Zia Pueblo indicate that the mesa now occupied by the tribe was first settled by their ancestors during the fourteenth century, when a neighboring site also was established by others of the same people. Except for a short period in the late seventeenth century when the group moved to a refugee site, occupation was continuous. In the east dump, sterile soil was encountered on the bottom of level 36 (each level of 25 cm. thickness); above this, five sloping zones with sherd complexes differing in proportions, if not always in types, could be traced.
