Fairfield, Utah
The town was founded in 1855 when John Carson, his four brothers, and others settled in the Cedar Valley. The settlement was soon known as Frogtown. The population ballooned after the arrival of Johnston's Army in 1858-59, sent to Utah to suppress the rumored rebellion there. The army established a nearby camp called Camp Floyd, and the population grew to over 7,000, including 3,500 troops (nearly one-third of the entire U.S. Army at that time), teamsters, gamblers, and camp followers of various persuasions.
