The Chamizal dispute was caused by a shift in which one of the principal rivers in the southwest United States and northern Mexico?
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.
Southern Athabaskan languages Southern Athabaskan (also Apachean) is a subfamily of Athabaskan languages spoken primarily in the Southwestern United States (including Arizona, New Mexico, Colorado, Utah) and the Mexican state of Sonora, with two outliers in Oklahoma and Texas. Those languages are spoken by various groups of Apache and Navajo peoples. In the northern versions, Athabaskan is spoken by many indigenous groups of peoples in Alaska and Canada. It represents the third major wave of ancient migration from Asia .
