Pah-Ute County is a former county in the northwest corner of Arizona Territory that existed from 1865 until 1871, at which point most of the area was transferred to Nevada. The remainder was merged into Mohave County. The majority of the territory is now in Clark County, Nevada, which includes the city of Las Vegas. Due to the transfer of most of the county's land to Nevada, Pah-Ute is sometimes referred to as Arizona's "Lost County". Pah-Ute is an historic spelling of the tribal name Paiute.
La Paz was a short-lived, early gold mining town along the Colorado River in La Paz County on the western border of the U.S. state of Arizona. It was the location of the La Paz Incident in 1863, the westernmost confrontation of the American Civil War. The town was settled in 1862 in New Mexico Territory, before the Arizona Territory was officially declared a United States territory by President Abraham Lincoln. Today it is a deserted ghost town. In 1983, long after the town was deserted, the name was adopted by the newly formed Arizona county of La Paz. La Paz is Spanish for "peace"; the town was presumably named after another earlier town named La Paz, such as La Paz, Bolivia, or La Paz, Baja California Sur.

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.

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 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.

In 1866, the road head changed to the new river landing of Ehrenburg, where the Bradshaw Trail wagon and stagecoach road from San Bernardino, California, crossed the Colorado River at Bradshaw's Ferry.
