"Rock Art" at Red Springs in Calico Basin, “Rock art” is the collective term for a variety of forms of visual representation made on natural rocky surfaces (boulders, cliff faces, cave walls, etc.) and are found throughout the world. Pictographs and petroglyphs represent the two main techniques used to make rock art. Pictographs are made through an additive process, where they are applied to the rock surface, and include paintings, charcoal drawings, stencils, prints. Petroglyphs are made by a reductive process, in which they are cut into the rock by engraving, pecking, incising or abrasion. Of the pictographs and petroglyphs that are found in Nevada, petroglyphs are by far the more common of the two. This may be the result of differential preservation as most of Nevada's pictographs are situated inside caves, rock shelters or other contexts, which afforded some measure of protection from the elements. -Online Nevada.org Uploaded on 9/25/2012 10:51:16 AM Made with Canon EOS 30D Digital SLR Camera © Dianne  Read Photo Discussion   |  Contact Dianne Dianne's Premium Gallery | Get Your Premium Gallery
