Excavations in the Santa Cruz River Floodplain


Book Description

Excavations in the Santa Cruz floodplain in 1995 provided important new data concerning the Middle Archaic period in southern Arizona. The work reported here represents the first intensive investigation of a stratified Middle Archaic site in the Tucson Basin. Eleven radiocarbon dates place the occupation between approximately 2600 and 1900 B.C. Analyses of the data collected shed new light on a number of important issues: subsistence and settlement immediately prior to the introduction of maize; the dating of the Middle Archaic interval itself; and the dating of Cortaro style projectile points, the dominant form represented at the site. The project also contributed significantly to knowledge of the Holocene depositional history of the Santa Cruz floodplain, particularly as it relates to the lengthy sequence of human occupation and use of this environment. CDA Anthropological Papers, No. 20 David A. Gregory is a staff archaeologist at Desert Archaeology, Inc. He has thirty years' experience in Arizona archaeology and has directed numerous projects in the Phoenix and Tucson basins.

The Davis Ranch Site


Book Description

In this new volume, the results of Rex E. Gerald’s 1957 excavations at the Davis Ranch Site in southeastern Arizona’s San Pedro River Valley are reported in their entirety for the first time. Annotations to Gerald’s original manuscript in the archives of the Amerind Museum and newly written material place Gerald’s work in the context of what is currently known regarding the late thirteenth-century Kayenta diaspora and the relationship between Kayenta immigrants and the Salado phenomenon. Data presented by Gerald and other contributors identify the site as having been inhabited by people from the Kayenta region of northeastern Arizona and southeastern Utah. The results of Gerald’s excavations and Archaeology Southwest’s San Pedro Preservation Project (1990–2001) indicate that the people of the Davis Ranch Site were part of a network of dispersed immigrant enclaves responsible for the origin and spread of Roosevelt Red Ware pottery, the key material marker of the Salado phenomenon. A companion volume to Charles Di Peso’s 1958 publication on the nearby Reeve Ruin, archaeologists working in the U.S. Southwest and other researchers interested in ancient population movements and their consequences will consider this work an essential case study.
