Cultural Resources Resurvey, Relocation, Assessment, and Evaluation of 16 Archaeological Sites for the Hayden Rhodes Aqueduct Phase IV Small Sites Assessment, Central Arizona Project Canal, Maricopa and La Paz Counties, Arizona

The Phoenix Area Office (PXAO), Reclamation, maintains an archaeological site database for the Central Arizona Project (CAP) main stem canal. The data base was developed using all the previous main stem survey data and previously recorded sites. While many sites have been determined eligible or not eligible for the National Register of Historic Places (Register), some have not received eligibility determinations and some are located outside of the construction corridor and not impacted. Additionally, legacy survey and site records have a number of errors and are sometimes contradictory.
When work on the Hayden Rhodes section of the CAP was initiated in the 1970s, contract archaeology was still in its infancy, with field methods and recording procedures still developing. Some of the sites along the Hayden Rhodes Aqueduct were recorded as low density artifact scatters encompassing hundreds of acres. Most of these sites have been resurveyed and site boundaries updated in a more discreet manner. Reclamation requested that Archaeological Consulting Services, Ltd. (ACS) relocate the remaining small sites found along the Hayden Rhodes Aqueduct between Phoenix and the Colorado River as part of this final phase of the assessment study.
Reclamation identified 16 sites to re-locate and assess the condition of these archaeological sites within the CAP ROW. This is the fourth and final phase of site assessments along the western reach of the CAP. Only the portions of sites found on Reclamation lands (including within the CAP security fence) were relocated, surveyed, and evaluated. All sites were re-surveyed, mapped, and their locational information updated with Universal Transverse Mercator (UTM) coordinates through Global Positioning System (GPS). Site existence or destruction was determined, as well as current conditions and how much of each site exists within the ROW. Register eligibility recommendations were made and site number discrepancies resolved with new Arizona State Museum (ASM) site numbers assigned, when necessary.
The purpose of this resurvey was to correct historic records, site maps, and locational errors. In general, these legacy records from the 1970s and 1980s were incomplete. AZSITE, ACS’s extensive library of cultural resource management (CRM) reports, and reports available online at the Digital Archaeological Record (tDAR) were examined to consolidate as many of these legacy records as possible into this final report. Sites that were not relocated or confirmed as no longer existing within Reclamation lands and/or the CAP ROW were identified and explained.

美国垦务局（Reclamation）凤凰城地区办事处（Phoenix Area Office, PXAO）维护着中亞利桑那调水工程（Central Arizona Project, CAP）主干渠的考古遗址数据库。该数据库依托既往所有主干渠勘测数据与已记录遗址构建而成。尽管多数遗址已被认定符合或不符合《国家历史遗迹名录》（National Register of Historic Places）的收录标准，但仍有部分遗址未完成资格审定，另有部分遗址位于施工廊道之外，未受工程影响。此外，既往勘测与遗址记录存在诸多错误，且部分内容相互矛盾。
20世纪70年代启动CAP海登·罗兹（Hayden Rhodes）段工程时，合同考古尚处于起步阶段，野外作业方法与记录规程仍在完善之中。海登·罗兹渡槽沿线的部分遗址曾被记录为覆盖数百英亩的低密度人工制品散布点，其中多数遗址已完成复测，并以更严谨的方式更新了遗址边界。垦务局委托考古咨询服务有限公司（Archaeological Consulting Services, Ltd., ACS）对菲尼克斯与科罗拉多河之间海登·罗兹渡槽沿线剩余的小型遗址进行点位核实，作为本次评估研究最终阶段的工作内容。
垦务局选定16处遗址，对CAP法定用地范围（CAP ROW，即Right of Way）内的这些考古遗址开展点位复核与状态评估。本次工作为CAP西段遗址评估的第四阶段，亦是最终阶段。仅对位于垦务局土地范围内（含CAP安全围栏内侧）的遗址区域实施点位复核、勘测与评估。所有遗址均完成复测与制图，并通过全球定位系统（Global Positioning System, GPS）获取通用横轴墨卡托（Universal Transverse Mercator, UTM）坐标系，更新了遗址的位置信息。本次工作确定了遗址的现存/损毁状态、当前保存状况，以及法定用地范围内各遗址的留存占比。研究人员针对遗址的名录收录资格提出推荐意见，并解决了遗址编号不一致的问题，必要时将为遗址赋予新的亚利桑那州立博物馆（Arizona State Museum, ASM）编号。
本次复测的核心目的为修正历史记录、遗址地图与位置信息中存在的错误。总体而言，这批20世纪70至80年代的既往记录存在信息不全的问题。研究人员对AZSITE——ACS旗下覆盖全面的文化资源管理（Cultural Resource Management, CRM）报告数据库，以及可通过数字考古记录（Digital Archaeological Record, tDAR）在线获取的报告进行梳理，尽可能将上述既往记录整合至本最终报告中。对于未能完成点位复核，或经确认已不在垦务局土地及/或CAP法定用地范围内的遗址，研究人员均予以列明并作出说明。
