History
The town of California Junction traces its origins to the Yazoo post office and the ill-fated towns of Cincinnati and Parrish City, which were founded in Cincinnati township during the later half of the 1850s. Yazoo Landing was a ferry crossing on the Missouri River where the Blair Bridge now stands. The present settlement was established in 1880, after the Sioux City and Pacific Railroad was built. John I. Blair, the railroad tycoon, believed that this would be an important hub for passengers heading west, and gave the town its current name. In 1883, the name of the town was changed to "California" to avoid confusion with Columbia Junction; it retained this name as of 1915.

In 1879, California Junction had a population of 200 people; the population was 76 in 1902. In 1903, the California Grain and Lumber Company was organized in California Junction. By 1915, there was also a town hall, high school, general store, blacksmith shop, post office, two churches, and a train station.

On January 1, 1922, a 1460-foot deep well was drilled at the nearby oil prospect of Hugh R. Coulthard, a prominent landowner, businessman, and farmer from California Junction. No oil was obtained from the site, but the capped well leaks water to this day. A marshy area surrounding the well remains as a local landmark, which is visible about 160 yards north of town on Fremont Ave., about 30 yards west of the roadway.

In 1925, California Junction's population was 84. The population was 100 in 1940.

A grain elevator is still operated at California Junction by the United Western Coop.
