This paper summarizes research on the potential of high-resolution imagery downloaded from Google Earth Pro to detect prehistoric canals from the Hohokam Period in the Middle Gila River Valley, Arizona. The potential of the imagery to identify obscured features was evaluated by means of ground truthing reconnaissance as well as a comparative analysis of the Google Earth imagery with the more traditionally employed CORONA and Landsat ETM+ imagery used in analogous studies. This research is presented as a method-based solution to utilize remote sensing in exploratory archaeological research projects facing budget constraints. The conclusion of the research was that Google Earth imagery provided the best spatial resolution for detecting obscured irrigation features compared to the other imagery used. The results of the investigation are summarized as a potential research model applicable in other dryland settings.
