El Morro National Monument is a U.S. national monument in Cibola County, New Mexico, United States. Located on an ancient east–west trail in the western part of the state, the monument preserves the remains of a large prehistoric pueblo atop a great sandstone promontory with a pool of water at its base, which subsequently became a landmark where over the centuries explorers and travelers have left personal inscriptions that survive today.
