Ammon, Idaho

Ammon was founded as South Iona back in 1889 by members of the Mormon church. The name South Iona came because in those days, there weren't enough people in the area to separate a separate ward of the church, so the settlers were members of the Iona Ward. The town was separated from Iona and given its own ward before Ammon was incorporated in 1905.

Ammon was an early agricultural center with a spur line of the Eastern Idaho Railroad leading to the Ammon grain elevator. There were several general stores and a brickyard to serve the approximately 1,100 people in the area by 1930. For most things though, folks made the trip to either Iona or to Idaho Falls.

Ammon grew slowly until the 1990's when Idaho Falls started to take off as a center for high-tech industry. As a bedroom community for Idaho Falls, Ammon has more than doubled in population since 2000.
