The uniformly light color of the sandstone surfaces explains why the Neolithic artists had to incise or peck the images deeply into the rock: so that sunlight raking across them would cast shadows demarcating the outlines of the figures.

However, all is not lost, and it is possible to establish a temporal sequence that can be quite edifying.In this case, a rock art panel may be judged to be younger, older or basically contemporaneous with another petroglyph, a site, an artifact, or other evidence of known antiquity.Relative dating, although somewhat less satisfying than absolute dating in terms of precision, is considerably more successful for petroglyphs.Around 10,0000 BCE, a significant climate change occurred, altering environments, flora, and fauna in most parts of the world.Following the Pleistocene, the Holocene or Recent epoch, witnessed a marked global warming that we still experience today.The patina is darker on the older images and the newer images are brighter.

Although it is difficult to state the absolute ages of most of the rock art studied in this project, there are certainly general trends, best estimates and bracketing dates, which will be provided whenever possible.

By scratching through the varnish and revealing the lighter colored underlying rock, it was possible to create bold images.

Many of the rock outcrops bearing Neolithic images never developed dark desert varnish at all.

The earth at that time was considerably colder and the ice caps were much larger than they currently are.

Many species, such as mammoth and woolly rhinoceros thrived in Eurasia and the mammoth, mastodon, camel and giant sloth lived in North America.

Clues to relative dating include: the manufacturing technique used; the patina covering the art; the layering of figures on top of each other; the style of human forms; and the particular animal species, types of artifacts and subject matter shown.
