'X' marks the approximate site of the legendary but short-lived gold mining town of La Paz, Arizona. La Paz was established in 1862 on the eastern bank of the Colorado River after gold was discovered nearby. It became the largest town in Arizona Territory with a population of 1,500 in 1864. It was the county seat of Yuma County, and for a time was a candidate to be the territorial capital. La Paz was a major transportation and supply hub, being a stop on the stagecoach line between San Bernardino, California, and Fort Whipple (Prescott), and a landing for steamship traffic on the Colorado River.
The gold mines played out by 1864, and in 1866 a flood shifted the course of the Colorado River miles away from La Paz, leaving it landlocked. The post office closed in 1875 and the town was abandoned. A new river landing was established at Mineral City (soon renamed Ehrenberg), six miles southwest of La Paz.
The La Paz name was revived in 1983 when the northern half of Yuma County was split off to form La Paz County.
