Culture and Ecology of Chaco Canyon and the San Juan Basin

Explaining Pueblo Social Organization 297Canyon early and recognize that mobility was anoption that could be employed at different times anddifferent places, we can begin to evaluate the diversityin material culture from a new perspective. Becausea dependence on hunting and collecting was probablyalways present, Gwinn Vivian's (1989, 1990) proposalof dual sequential hierarchy may weB have operatedearly, but it might not have been formalized until themid-eleventh century. Determining the individualtrajectories of different groups and modeling the socialorganization pose a challenge and provide many opportunitiesto study the Pueblo World. I hope that thenext generation makes as many inroads into understandingthis durable yet flexible history of the earlyPueblo peoples as the Chaco Project scholars did.
