Chamizal boundary dispute caused by Rio Grande shifts

The Chamizal National Memorial commemorates the long-running boundary dispute between the United States and Mexico in the El Paso–Juárez area that arose when the Rio Grande changed course, transferring land between the two countries. The 1963 Chamizal Convention and subsequent land exchange resolved the dispute; the memorial marks the settlement and the altered river-created boundary. The site sits adjacent to the international boundary and interprets the geographical causes of the conflict.
