Natural Landmark in New Mexico
Protected and managed by the National Park Service, El Morro National Monument has been an important landmark to travelers for hundreds of years due to the reliable water hole at the base of a sandstone bluff. Over 2,000 signatures, dates, messages, and petroglyphs can be seen carved into the rock, authored by Ancestral Puebloans, Spanish and American travelers.
