Between the River and the Terrace: Archaeological Investigations Within the Red Mountain Freeway Corridor, From Gilbert Road to Higley Road


This report discusses the results of archaeological testing at four cultural resource sites to assess their eligibility for inclusion in the National Register of Historic Places (NRHP), and the results of data recovery excavations at one of the four sites to mitigate impacts from construction. Entranco completed this project at the request of the Arizona Department of Transportation (ADOT) prior to the proposed construction of the Red Mountain Freeway (RMF) Gilbert Road to Higley Road segment between October 2000 and March 2001. The RMF project is being funded by the Federal Highway Administration (FHWA), and as such is a federal undertaking subject to the Section 106 process, 36 CFR § 800.16 (y), the regulations implementing the National Historic Preservation Act (NHPA).

As discussed in this document, the RMF corridor encompasses the entire freeway right-of-way (R/W) and consists of areas that will be disturbed by construction of the freeway, and areas that will not be disturbed. The investigated sites included AZ U:9:226 (ASM), AZ U:10:117 (ASM), AZ U:10:122 (ASM), and AZ U:10:123 (ASM). Testing and data recovery results were previously presented in multiple preliminary reports and submitted to ADOT and consulting parties in order to allow construction to proceed on schedule.

This final report is comprehensive and describes the investigations conducted at each site, the results of all fieldwork and analyses, and the interpretation of the accumulated data to address research questions that were posed for each site. Importantly, the results of archival research also Indicate that 1) the features Identified at AZ U:9:226 (ASM) during current investigations do not represent the site that was historically recorded in that location on Turney’s 1929 map of the Salt River valley and 2) there is no historical basis for designating AZ U:9:226 (ASM) as either T-9 or Casas del Oriente as it occurs in the previous literature.
