miles (13 km) north of El Paso. The treaty was based on an 1847 copy (the Disturnell Map) of a twenty-five-year-old map which was incorporated into the treaty. However, surveys revealed that El Paso was 36 miles (58 km) further south and 100 miles (160 km) further west than the map showed. Mexico favored the map, but the United States put faith in the results of the survey. The disputed territory involved a few thousand square miles and about 3,000 residents; more significantly, it included the Mesilla Valley. Bordering the Rio Grande River, the valley consisted of flat desert land measuring about 50 miles (80 km), north to south, by 200 miles (320 km), east to west. This valley was thought to be essential for construction of a transcontinental railroad using a southern route.

When the Sonora Exploring and Mining Company opened silver mines in southern Arizona, it sought to employ educated, middle-class Americans who shared a work ethic and leadership abilities to operate the mines. A biographical analysis of some 200 of its employees, classed as capitalists, managers, laborers, and general service personnel, reveals that the resulting work force included Europeans, Americans, Mexicans, and Indians. This mixture failed to stabilize the remote area, which lacked formal social, political, and economic organization in the years from the Gadsden Purchase to the Civil War. 756:, the United States negotiator, agreed to allow Mexico to retain the Mesilla Valley by setting the point at which the boundary commenced toward the west from the Rio Grande River at 32° 22′ N. This point was north of the American claim of 31° 52′ N and, at the easternmost part, also north of the Mexican-claimed boundary at 32° 15′ N, both also on the Rio Grande River). Bartlett's agreement to 32° 22′ N was in exchange for a boundary westward from the river that did not turn north until 110° W in order to include the Santa Rita del Corbe Mountains (sometimes referred to simply as the Corbe Mountains) located in current New Mexico east of current-day Silver City.

The fort protected the area until it was evacuated and destroyed in July 1861. The new stability brought miners and ranchers. By the late 1850s mining camps and military posts had not only transformed the Arizona countryside; they had also generated new trade linkages to the state of Sonora, Mexico. Magdalena, Sonora, became a supply center for Tubac; wheat from nearby Cucurpe fed the troops at Fort Buchanan; and the town of Santa Cruz sustained the Mowry mines, just miles to the north.

Acquiring trackage rights over the SP, from Deming to Benson, the Santa Fe then built a line southwest to Guaymas, Sonora, Mexico, completed October 1882, as its first outlet to the Pacific.

The Southern Pacific continued building east from El Paso, completing a junction with the Texas & Pacific in December 1881, and finally in 1883, its own southern transcontinental, the Sunset Route, California to New Orleans, Atlantic waters to the Pacific.

But these difficulties did force laws and associations in Arizona to curb and resolve them. The Anglo-American cattleman frontier in Arizona was an extension of the Texas experience.
