Arimo sits on the east side of Marsh Valley. Farms and ranches dot the valley, above which the imposing slopes of Old Tom Mountain rise to 8,600 feet. Behind the city, the slopes of another range of mountains rise gradually. In 1878, the Utah & Northern Railroad was extended to Arimo, following Marsh Valley northward toward Pocatello. For a time the population was as high as 2,000, due to the activity on the railroad. Originally called Oneida, Arimo was renamed in honor of an Indian chief.
Today Interstate 15 passes next to Arimo, supplanting the railroad as a transportation route. The population has dwindled to 348 and there is a quietness about the town.
