Nevada rock art is found in a wide variety of landscapes and locations throughout the state.

Few sites in Nevada provide clear contextual indications of their date of production and period of use, such as stratigraphic superimposition by datable materials.

Texas A&M chemist Marvin Rowe found that seven of the samples had sufficient carbon to provide data for analyses; these returned dates ranging from 1350 ± 160 years ago to 740 ± 50 years ago.Most fall within the earliest phase of the Formative period, the Mesilla phase, and others fall within the transitional, or Dona Ana phase, the time of the Hueco Tanks villagers.Another difficulty with radiocarbon dating rock art is the possibility of carbon contamination of the pigment samples submitted for testing.Many Native Americans believe that their ancestors were created here at the beginning of time, but most archaeologists agree that people have lived in Nevada for at least 10,000-12,000 years.Of the pictographs and petroglyphs that are found in Nevada, petroglyphs are by far the more common of the two.
