An intensive archeological survey of about 7.7 mi. of Salt River Project (SRP) Coronado-Silverking 500 KV transmission line easement extending from just east of the Sitgreaves National Forest to the APS-SRP Joint Corridor was conducted by Museum of Northern Arizona archeologists in December, 1977. The survey was requested by Bettina Rosenberg, SRP Archeological Administrator, in a letter dated December 12, 1977. The survey was conducted and this report prepared under the stipulations and guidelines of the Cultural Resources Plan developed by the National Forest Service NFS) for the Coronado Project (1977). At the time of the survey, tower locations had not been plotted; therefore, the survey area consisted only of the 200 ft. right-of-way corridor. After tower locations have been determined as a result of consultations between SRP and the NFS, an archeological team will return to the field and survey the access roads and a 200 ft. radius around each tower. Field collection was not permitted by the Forest Service during this survey, so that in-depth lab analysis of the sites was not possible. Also, site interpretation on the basis of survey alone is usually questionable. However, background material concerning the environment and culture history of the project area may be found in the Environmental Impact Statement for the Coronado Station (Dames & Moore 1976).

At the request of Salt River Project, the Museum of Northern Arizona conducted an archaeological survey of Tonto National Forest lands to be impacted by the construction of the Silverking to Kyrene 500 kV and 230 kV transmission lines near Superior, Arizona. The impact areas surveyed consist of tower anchoring locations, pulling locations, access roads, and a wire set-up location. What appeared to be prehistoric check dams were observed at the pulling location and designated site NA15,784. No other archaeological materials or features were observed in the impact areas. Therefore, if the check dams are avoided during construction, archaeological clearance can be recommended for those areas to be impacted. Two versions of the same report. Version 2 includes an updated survey and results section.

The Museum of Northern Arizona conducted an archaeological survey of proposed pulling locations and a sleeving location on the Tonto National Forest. Since no artifacts or sites were observed, clearance is recommended. This is a final report.
