Chamizal dispute The Chamizal dispute was a border conflict over about 600 acres 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. The Chamizal was once the only link between El Paso and Ciudad Juárez and tensions over the territory during the historic Taft–Diaz summit almost resulted in the attempted assassination of both presidents on October 16, 1909.
Pasión River The Pasión River (Spanish: Río de la Pasión , ] ) is a river located in the northern lowlands region of Guatemala.

At this confluence the greater Usumacinta River is formed, which runs northward to its eventual outlet in the Gulf of Mexico. The Pasión River's principal tributaries are the San Juan River, the Machaquila River, and the Cancuén River.
