Cooke wrote of the Mormon Battalion, "History may be searched in vain for an equal march of infantry." Known as Cooke's Road or the Gila Trail but more currently known as the Mormon Battalion Trail, the wagon road was used by settlers, miners, stagecoaches of the Butterfield Stage line and cattlemen driving longhorns to feed the gold camps. Parts of the route became the Southern Pacific Railroad and U.S. Route 66. Currently, the Boy Scouts of America gives an award for those who hike sections of this historic trail. In February 1848, knowledge gained about the region was used as the basis of the Treaty of Guadalupe Hidalgo, which established the United States-Mexico border in December 1853, following the Mexican-American War.
