The border is approximately 372 miles long, and it runs from the Pacific Ocean to the Colorado River.
The Origin of the Border
The California-Arizona border has a complex history, which includes a variety of factors that have shaped its location and composition.

The Treaty of Guadalupe Hidalgo
The Treaty of Guadalupe Hidalgo, signed in 1848, marked the end of the Mexican-American War and established the southern border of the United States. This border followed the Rio Grande river, which meant that much of what is now Arizona and California remained part of Mexico until the Gadsden Purchase in 1853.
