Port Isabel was a seaport established on Port Isabel Slough in 1865 during the American Civil War in Sonora, Mexico in the mouth of the Colorado River on the Gulf of California. It was founded to support the increased river traffic caused by the gold rush that began in 1862 on the Colorado River and the Yuma Quartermaster Depot newly established in 1864 to support the Army posts in the Arizona Military District. The slough was discovered in 1865 by the Captain W. H. Pierson of the schooner Isabel, that first used the slough to transfer its cargo to steamboats safe from the tidal bore of the Colorado River. Shortly afterward Port Isabel was established 3 miles up the slough and replaced Robinson's Landing as the place where cargo was unloaded in the river from seagoing craft on to flat bottomed steamboats of the Colorado River and carried up to Fort Yuma and points further north on the river.
The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853.

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.
George Alonzo Johnson (1824–1903) was an American entrepreneur and politician.

Vallecito, in San Diego County, California, is an oasis of cienegas and salt grass along Vallecito Creek and a former Kumeyaay settlement on the edge of the Colorado Desert in the Vallecito 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.
The California Indian Wars were a series of wars, battles, and massacres between the United States Army, and the Indigenous peoples of California.

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.
