8km in Ciudad Juarez

The Chamizal dispute was a border conflict over about 600 acres (2.4 km2) on the Mexico–United States border between El Paso, Texas, and Ciudad Juárez, Chihuahua. It was caused by a shift in the Rio Grande, as a survey presented in 1852 marked differences between the bed of the Rio Grande (in Spanish: Río Bravo del Norte) and the present channel of the river.
