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.
Nevada Basin The Nevada Basin is the Great Basin area surrounded by river basins and, to the east, the Great Salt Lake basin (Pleistocene Lake Bonneville basin). The bounding river basins include those of the following (clockwise from south-southeast): Sevier River, Muddy River (Meadow Valley Wash, White River), Las Vegas Wash, Colorado River, Mojave River, Amargosa River, Owens River, Lake Lahontan basin (Walker River, Carson River, Humboldt River, Reese River), and Snake River. The 1850 diagonal California state lines with the Utah Territory & New Mexico Territory are along the general direction of the Nevada Basin's southwest drainage divide (rim), while the north-to-south rim on the east is through the area of the three meridians (1861, 1862, & current 1864) used for the Nevada-Utah state line.
