A copper mine delves deep into the orange rock of an Arizona desert. More than a dozen even steps have been excavated leading down to a roughly circular depression in the ground. Some of the steps have patches of oxidized copper, a blue-green color. A smooth path large enough for heavy machinery spirals down into the bottom of the mine.
