Interstate 8 (I-8) is an Interstate Highway in the southwestern United States. It runs from the southern edge of Mission Bay at Sunset Cliffs Boulevard in San Diego, California, almost at the Pacific Ocean, to the junction with I-10, just southeast of Casa Grande, Arizona. In California, the freeway travels through the San Diego metropolitan area as the Ocean Beach Freeway and the Mission Valley Freeway before traversing the Cuyamaca Mountains and providing access through the Imperial Valley, including the city of El Centro. Crossing the Colorado River into Arizona, I-8 continues through the city of Yuma across the Sonoran Desert to Casa Grande, in between the cities of Phoenix and Tucson.
Butterfield Overland Mail was a stagecoach service in the United States operating from 1858 to 1861. It carried passengers and U.S. Mail from two eastern termini, Memphis, Tennessee, and St. Louis, Missouri, to San Francisco, California. The routes from each eastern terminus met at Fort Smith, Arkansas, and then continued through Indian Territory (Oklahoma), Texas, New Mexico, Arizona, Mexico, and California ending in San Francisco. On March 3, 1857, Congress authorized the U.S. postmaster general, at that time Aaron V. Brown, to contract for delivery of the U.S. mail from St. Louis to San Francisco. Prior to this, U.S. Mail bound for the Far West had been delivered by the San Antonio and San Diego Mail Line since June 1857.
Fort Yuma was a fort in California located in Imperial County, across the Colorado River from Yuma, Arizona. It was on the Butterfield Overland Mail route from 1858 until 1861 and was abandoned May 16, 1883, and transferred to the Department of the Interior. The Fort Yuma Indian School and the Saint Thomas Yuma Indian Mission now occupy the site. It is one of the "associated sites" listed as Yuma Crossing and Associated Sites on the National Register of Historic Places in the Yuma Crossing National Heritage Area. In addition, it is registered as California Historical Landmark #806.

Southern Emigrant Trail, also known as the Gila Trail, the Kearny Trail, Southern Trail and the Butterfield Stage Trail, was a major land route for immigration into California from the eastern United States that followed the Santa Fe Trail to New Mexico during the California Gold Rush. Unlike the more northern routes, pioneer wagons could travel year round, mountain passes not being blocked by snows; however, it had the disadvantage of summer heat and lack of water in the desert regions through which it passed in New Mexico Territory and the Colorado Desert of California. Subsequently, it was a route of travel and commerce between the eastern United States and California. Many herds of cattle and sheep were driven along this route and it was followed by the San Antonio-San Diego Mail Line in 1857–1858 and then the Butterfield Overland Mail from 1858 to 1861.
The San Antonio–San Diego Mail Line, also known as the Jackass Mail, was the earliest overland stagecoach and mail operation from the Eastern United States to California in operation between 1857 and 1861. It was created, organized and financed by James E. Birch the head of the California Stage Company. Birch was awarded the first contract for overland service on the "Southern Route", designated Route 8076. This contract required a semi-monthly service in four-horse coaches, scheduled to leave San Antonio and San Diego on the ninth and the 24th of each month, with 30 days allowed for each trip.
The Butterfield Overland Mail was a transport and mail delivery system that employed stagecoaches that travelled on a specific route between St. Louis, Missouri and San Francisco, California and which passed through the New Mexico Territory. It was created by the United States Congress on March 3, 1857, and operated until March 30, 1861. The route that was operated extended from where the ferry across the Colorado River to Fort Yuma Station, California was located, through New Mexico Territory via, Tucson to the Rio Grande and Mesilla, New Mexico then south to Franklin, Texas, midpoint on the route. The New Mexico Territory mail route was divided into two divisions each under a superintendent. Tucson was the headquarters of the 3rd Division of the Butterfield Overland Mail Company. Franklin Station in the town of Franklin,, was the headquarters of the 4th Division.
The Butterfield Overland Mail route in Baja California was created as a result of an act by the United States Congress on March 3, 1857, and operated until June 30, 1861 as part of the Second Division of the route.

Vallecito, in San Diego County, California, is an oasis of cienegas and salt grass along Vallecito Creek and a former settlement on the edge of the Colorado Desert in the Vallecito Valley. Its Spanish name is translated as "little valley". Vallecito was located at the apex of the gap in the Carrizo Badlands created by Carrizo Creek and its wash in its lower reach, to which Vallecito Creek is a tributary. The springs of Vallecito, like many in the vicinity, are a product of the faults that run along the base of the Peninsular Ranges to the west.

Steamboats on the Colorado River operated from the river mouth at the Colorado River Delta on the Gulf of California in Mexico, up to the Virgin River on the Lower Colorado River Valley in the Southwestern United States from 1852 until 1909, when the construction of the Laguna Dam was completed. The shallow draft paddle steamers were found to be the most economical way to ship goods between the Pacific Ocean ports and settlements and mines along the lower river, putting in at landings in Sonora state, Baja California Territory, California state, Arizona Territory, New Mexico Territory, and Nevada state. They remained the primary means of transportation of freight until the advent of the more economical railroads began cutting away at their business from 1878 when the first line entered Arizona Territory.

Antelope Peak Station, a later Butterfield Overland Mail station located 15.14 miles east of Mission Camp, at the foot of Antelope Peak. It replaced Filibusters Camp Station, 6 miles to the west. The Overland Mail Company replaced Filibusters Camp, because Antelope Peak Station had a better water supply. Its location is thought to be 32°42′47″N114°00′54″W. The station was built by John Kilbride in 1857 but did not appear on the stagecoach itinerary until 1859.
