This was an intensive study of a single mountain range rich in petroglyph sites. One hundred nineteen sites with over 2,000 designs were recorded. Unsuccessful attempts were made to find significant positive correlations between such factors as design associations, site locations and concentrations, and environmental influences. The study produced some evidence that the probable originators of the petroglyphs were the Hohokam farmers who occupied the area for approximately the first 1500 years A.D.
