Archaeological Investigations in the Tinaja Hills, Pima County, Arizona

Author(s): R. Thomas Euler; Earl W. Sires

Year: 1989


This report presents project background information and the results of investigations conducted at five archaeological sites located in the Tinaja Hills of southern Arizona. These investigations (SWCA Project No. 88-15) were conducted during January, February, and March of 1989, by SWCA, under contract with Celia Barr Associates of Tucson, Arizona. These investigations were necessitated by the fact that the project area is currently under development as the Arizona Proving Grounds for Caterpillar, Inc. of Phoenix, Arizona. It was anticipated that this development might result in adverse impacts to these sites. The five sites were first identified and recorded during a survey conducted by SWCA during June and July, 1988 (Euler 1988). This survey was also conducted under contract with Celia Barr Associates as part of the Arizona Proving Grounds planning process.

Site evaluations and surface collections were conducted at two of these sites [AZ DD:4:124 (ASM) and AZ DD:4:148 (ASM)]. These activities included detailed mapping and controlled collection of a sample of surface artifacts. This work was conducted by a crew of four archaeologists and required 36 person-field days for completion.

It was determined that three other archaeological sites [AZ DD:4:133 (ASM), AZ DD:4:135 (ASM), and AZ DD:4:137 (ASM)] could not be avoided during planned construction associated with the development. These sites would consequently be impacted. At the request of Celia Barr officials, SWCA applied to the State Lands Archaeology Office at the Arizona State Museum for permits to conduct limited archaeological testing on these sites (State Permit No. 89-16). The purpose of this testing program was to determine the presence or absence of significant subsurface deposits as they relate to Arizona State and National Register criteria.

The test excavations were conducted between February 21 and March 1, 1989, by SWCA. The work was conducted by a crew of five archaeologists and required 31 person-field days to complete.
