Petroglyphs are evidence of the ancient inhabitants of the American continent. In the desert Southwest, the climatic conditions are optimal for the preservation of these artifacts. Fortunately, many examples of this ancient rock art have been preserved. Fortunately, many of the petroglyph sites are so remote as to be inaccessible. In other cases, the rock art easily approached but nearly impossible to see. You have to look carefully at all the rock surfaces that might have been used. For the Colorado Plateau states, Arizona, Utah, Colorado and New Mexico, there are a number of guidebooks showing the locations of concentrations of rock art.
