Alto, Arizona

A ghost town in Arizona. Alto is a ghost town in Santa Cruz County, Arizona, first settled in the early 1900s in what was then part of the Tyndall Mining District, east of Tubac in the Santa Rita Mountains. The town was originally named El Plomo, which is Spanish for "lead", and was changed to Alto, meaning "high", many years later, probably because the mines were located high up on a steep mountainside.
