The town of Mace's Hole was settled in 1862. The town was named for Juan Maes, anglicized to "Mace," a bandit who used the valley for a hideout. The Mace's Hole Post Office opened on April 23, 1873. A local preacher took umbrage at the town's name and suggested the biblical name Beulah as a more wholesome alternative. The name of the town was changed to Beulah on October 25, 1876. The name is a reference to Isaiah 62:4; it comes from the Hebrew for "married."
