The story of Mammoth

Utah's ghost towns split between the Mormon agricultural villages that failed and the mining camps that boomed. The camps — Park City's silver, Bingham's copper, the coal towns of Carbon County — drew a rougher crowd than Brigham Young's orderly settlements, and they lived by rougher rules. Mammoth, out in Juab County County, belongs to the mineral side of that divide: a place that existed because something valuable was in the ground, and stopped existing when it wasn't. The transcontinental railroad's completion at Promontory in 1869 made it all possible, hauling machinery in and ore out — and when the mines closed, the same rails carried everyone away.
