The old mining town of Superior dates back to 1875, when Aaron Mason discovered silver in what eventually became the Silver King Mine. The town lies to the west of scenic Queen Creek Canyon. It was featured in the 1997 Oliver Stone film "U-Turn".
The Magma Copper Mine in Superior has a shaft nearly 5,000 feet deep. The warm rock formation created a need that brought about the first air-conditioned mine in North America, improving health and safety factors in mine operations and making deeper excavation possible.
The ghost town of Pinal City was once the mill town for the Silver Creek Mine, located along Queen Creek. A few grave markers and wagon ruts are all that remain today.
