The technology of the dominant society, the omnipresence of a cash economy, and a history of the brutal treatment of culturally distinct peoples are among the assimilative pressures faced by native peoples within the United States. Some indigenous cultures have managed to resist the forces of assimilation in ways that are both adaptive and culturally sustaining. The Pueblos of the Southwestern United States have managed to preserve their culture through the creation of cultural boundaries that are both adaptive and culturally sustaining. The processes which serve to strengthen and renew the symbols which represent these boundaries are those of "revitalization" and "resynchronization," both of which arise from Pueblo religious practices and from the Pueblos' strong sense of family. / Department of Anthropology

In the Paria Plateau area of northern Arizona and southern Utah the Chinle formation of Upper Triassic age consists of a thick series of Ienticular sandstone, siltstone, claystone, and limestone. The series thins northwestward from about 900 feet at Lees Ferry, Ariz., to about 800 feet at Paria, Utah. Four members of the Chinle formation are recognized—1) the basal Shinarump member composed of conglomeratic sandstone and subordinate shale, 2) a unit, herein named the Lowery Spring member, composed of sandstone and mudstone, 3) the Petrified Forest member composed of bentonitic siltstone and claystone and thin sandstone, and 4) the Owl Rock member composed of cherty limestone and calcareous siltstone. Only the Petrified Forest member is present at all localities in the Paria Plateau area. The Shinarump member was deposited in topographic low areas on an erosion surface and its distribution is irregular. The Lowery Spring and Owl Rock members grade and pinch-out toward the northwest and are not present at Paria, Utah. The upper contact of the Chinle formation is locally unconformable. The three lowermost members were deposited on a broad, flat plain between the Cordilleran geosyncline and highlands to the southeast. In Owl Rock time the rising Cordilleran geanticline cut off the north-westward drainage of Chinle streams and a depositional basin trending southwest was formed.

Throughout the colonial period, the Spanish attempted to Hispanicize the Indians along the northern frontier of New Spain. The conquistador, the missionary, the civilian settler, and the presidial soldier all took part in this effort. At La Junta de los Rios, a fertile area inhabited by both sedentary and semi-sedentary Indians, each of these institutions played a part in fundamentally changing the region and its occupants. This research, relying primarily on published Spanish source documents, sets the effort to Hispanicize La Junta in the broader sphere of Spain's frontier policy.
