LeRoy Unglaub’s topic, sponsored by the El Paso Archaeological Society, is “Rubbing Rocks and Rock Art”. In a PowerPoint presentation he will show many rock art sites in southern New Mexico and west Texas which have associated boulders and rock faces that are highly polished. LeRoy will present evidence that these polished surfaces, called rubbing rocks, were made by large animals and mega fauna. Photographs showing how to identify rubbing rocks, examples of rubbing rocks and their associated rock art (pictographs (painted images) and petroglyphs (pecked images)) at a number of sites, and any correlation between the rock art and rubbing rocks will be briefly discussed.

LeRoy Unglaub is a retired electronics engineer who got bitten by the rock art bug about twenty five years ago. He is involved in the study, photography, and documentation of rock art sites. He is a member of the American and Utah Rock Art Research Associations and of several archaeological societies. He has given presentations on rock art and other related subjects to archaeological and rock art societies as well as to other clubs and organizations.
