Ams dating rock art
There is some suggestion that scratched petroglyphs were made into historic times using metal instruments such as a nail or a knife.Very close examination of the incised line may reveal traces of metal within them verifying their historic age.The liquid pigment was applied to the rock surface using the fingertip or hand or possibly sticks with frayed ends or some other type of “brush.” Very few studies of pictograph materials or rock art dating have been conducted in Nevada, although these types of analyses have been done in other parts of North America.Petroglyphs Petroglyphs are produced by simply removing the very thin layer which covers the outer surface of rocks.Very few rock art sites offer thematic indicators of their age, such as the depiction of extinct animals, or the portrayal of diagnostic artifacts which forms the basis for identifying historic period rock art (for example the portrayal of wagons, people wearing cowboy hats and riding horses, etc.).
Such motifs are found throughout the world and form the basis of all visual traditions of art.Pictographs Colored minerals were used to make pigments for pictographs (ocher being the most common, but also gypsum, charcoal, etc.).These minerals were ground very finely and mixed with a wetting medium (called a binder), such as water.By giving a motif an interpretive label (e.g., calling a wavy line a “snake” or “river” or “path”) rather than a neutral descriptive label creates meanings that have more to do with the contemporary observer than the rock art's original makers and users.Additionally, the act of creation is only the first stage in rock art's cultural-use life—through time rock art is encountered and reinterpreted by later peoples, so its “meaning” is not necessarily inherent, but is instead constructed, negotiated, and reinterpreted for as long as it is perceived as having cultural resonance.
