The south side of Inscription Rock (now El Morro National Monument), in New Mexico in 1873. Note the small figure of a man standing at bottom center. The prominent feature stands near a small pool of water, and has been a resting place for travelers for centuries. Since at least the 17th century, natives, Europeans, and later American pioneers carved names and messages into the rock face as they paused. In 1906, a law was passed, prohibiting further carving.
