Ruby, Arizona is one of the best preserved ghost towns in Arizona, but you can only gain access to it by helping in the restoration effort. It was founded as a mining camp, producing mostly copper, lead and zinc. At its peak in the mid 30s, Ruby's population reached 1,200. The population diminished after the mine was closed in the 50s. The few buildings that remain include the jail, a schoolhouse, mine offices and a handful of homes.
