Do you know the difference?

…between a petroglyph and a pictograph? Here’s a hint, one is pecked, ground, incised, abraded, or scratched on the rock surface, and one is painted on the rock surface using mineral pigments and plant dyes.

Therefore, the following photo taken by Ken Fuhrer during last year’s Red Rock tour, is a fine example of a petroglyph.

Researchers estimate that some of the rock art found in this region dates to a few hundred years ago, while other examples go back 5,000 years.
