Coronado National Memorial

The Coronado National Memorial commemorates the first organized expedition into the Southwest by conquistador Francisco Vásquez de Coronado in 1540. The memorial is located in a natural setting on the Mexico–United States border on the southeast flank of the Huachuca Mountains south of Sierra Vista, Arizona and is bordered to the north and west by Coronado National Forest. Within the memorial is an overlook at Montezuma Pass where the Coronado expedition entered modern Arizona. The memorial confirms the ties that bind the United States and Mexico.
