Blacks Fork was established in 1870 as a logging camp that supplied lumber to the railroad and mining industries. A large barn was erected near the center of the town, and several businesses and homes were built around the barn. Tradition says that the town also served as a military commissary during the early part of its history, but Utah ghost towns researcher Stephen Carr concluded that "...this suggestion is very unlikely," citing the camp's remote location and harsh climate, as well as the fact that an army post called "Blacks Fork" already existed near Bryan, Wyoming. The population peaked at about 100, but the town was soon abandoned. Remaining are the barn, a post office, and a few homes.
