Arizona is a land of diverse landscapes, often strikingly juxtaposed. In the upper Gila River Valley of southeastern Arizona, the basin surrounding the modern town of Safford encompasses the intersection of different environments and prehistoric cultures. The Hohokam of the Sonoran Desert, Mogollon of the San Simon Valley and mountain highlands, Anasazi of the Colorado Plateau, and Apache of the mountains and plains all lived in this region during the Ceramic period, A.D. 600-1450. Crossroads of the Southwest presents the results of new archaeological research that sets aside long-standing theoretical constraints to examine anew three central themes in Southwestern archaeological study-culture, identity, and migration. Six innovative studies by top regional scholars utilize both new data and classic studies to examine a region long overlooked by archaeologists.
