This chapter presents a case study from the field of cultural resource management that provides a recent example of how geographical information systems are being used in the remote and undeveloped State of Alaska, United States. The Alaska State historic preservation office within the Office of History and Archaeology requires location models to be devised for large, multi-year projects. The proposed Susitna-Watana Dam Project would be located on the Susitna River roughly 90 river miles north of Talkeetna, Alaska. The chapter reviews the project scope of works, available literature, and satellite/aerial photography to identify locations where archaeological materials are located within and surrounding the project area. The ethnogeographic portion of the 2013 study included direct consultation with Ahtna elders in order to integrate Alaska Native perspectives on historical land use and cultural values into the ongoing cultural resource investigation.
