This volume serves two purposes. It summarizes the subsistence data from the RPMS project and explores what we have learned from the subsistence-related data from the RMPS investigations, as well as the related Roosevelt Rural Sites Study and the Community Development Study. The Roosevelt Platform Mound Study (RMPS) research design was particularly concerned with Classic period sociopolitical organization. Because platform mounds similar to those of the Hohokam were built across the basin during the Classic period, an overarching theme concerned the nature and extent of sociopolitical complexity. A number of implication for patterning in the diet and subsistence data were derived from general models concerning the behavior of aspiring elites in the basin. In particular, subsistence data were expected to inform on three aspects of sociopolitical complexity: the capacity for surplus production; the existence of a specialized economy; and the activities of elites at the platform mound sites.

Between 1989 and 1993, the Bureau of Reclamation funded four archaeological projects in Tonto Basin of central Arizona, all associated with the modification of the Theodore Roosevelt Dam. The projects were assigned different research objectives and were conducted by separate research teams. The Roosevelt Bajada Survey (RBS) was a sampling survey by SWCA Inc. of portions of the bajada and foothills surrounding Tonto Basin. The Roosevelt Rural Sites Study (RRSS) conducted by Statistical Research focused on small agricultural and habitation sites in the rural areas away from the large settlements in the basin. Desert Archaeology Inc. of Tucson was responsible for the Roosevelt Community Development Study (RCDS), and their aim was to provide a longitudinal record of the history of occupation of Tonto Basin. The Roosevelt Platform Mound Study (RPMS), conducted by the Office of Cultural Resource Management at Arizona State University (ASU), studied the organization of Classic period platform mound complexes. As the study progressed, Reclamation modified the Platform Mound Study to include the investigation of a series of 44 sites on the bajada that had been identified in the survey conducted by SWCA. This volume draws on the results of the various projects to test propositions about Tonto Basin prehistory and it identifies areas in which differences in analyses lead to incomparable sets of results. The emphasis is on empirically testing each proposition; analogy to historic and ethnographic examples is an excellent basis for suggesting hypotheses about the past, but it does not substitute for tests of archaeological hypotheses using archaeological data. The Roosevelt archaeology projects amassed data on a truly remarkable scale, and those data were used to test a number of hypotheses about prehistoric society. Many of the hypotheses formulated to glide the research were rejected, and the results led to unexpected views on how the populations in Tonto Basin were organized and how they related to the populations of the surrounding regions. Several hypotheses, for instance, dealt with the degree of cooperation that ought to occur between settlements in trade or subsistence, positing there was either a lot or only a little cooperation. None of these hypotheses prepared us, however, for the finding that relationships among settlements were often highly competitive. People in Tonto Basin competed for agricultural land, trade contacts, and ultimately for occupancy of the basin itself. This volume is written by members of the Platform Mound Study team but is intended as a summary of the results of all four Reclamation projects. There is, as a consequence, no stand-alone synthesis for the Platform Mound Study. Members of the research team have incorporated summaries of the results in the site description volumes for the study, and readers are referred to those volumes for summaries that pertain specifically to the RPMS.

This report is the fifth site description volume for the Roosevelt Platform Mound Study and describes archaeological investigations at Cline Terrace Mound. Cline Terrace Mound is part of the Cline Terrace Complex, which is located at the northwestern end of the Tonto Basin, along the eastern bank of Tonto Creek. Cline Terrace Mound is the largest site in the complex and is located in its middle, with many other sites in the areas to the northwest and southeast along Tonto Creek. The smaller sites in the Cline Terrace Complex are described in Volume 9 of the Roosevelt Platform Mound Study, "Salado Settlements on Tonto Creek, Roosevelt Platform Mound Study, Report on the Cline Mesa Sites, Cline Terrace Complex."

This two-part report is the seventh and final site description volume for the Roosevelt Platform Mound Study, an eight-year archaeological research project in the Tonto Basin of central Arizona that began in April 1989. It was funded by the Bureau of Reclamation, Department of the Interior, and was conducted by the Office of Cultural Resource Management in the Department of Anthropology at Arizona State University. The work was performed under a permit from the Tonto National Forest. The Cline Mesa sites reported in this volume were in the Cline Terrace Complex. The Cline Mesa sites total 35 in number and include all sites in the Cline Terrace Complex with the exception of Cline Terrace Mound, the large platform mound in the center of the complex.
