Petroglyphs date back thousands of years and are found all over the world.
They were used by early man to record events, visions and story telling. They were produced using crude tools such as sticks, rocks or bone. Such pictures convey ideas or meaning to the mind without the use of words, sounds or other language form. Indians found North of the Rio Grande had no written language. They managed to keep alive traditions and tell stories by passing them down by word of mouth.
