Book excerpt: The famous legend of the Iron Door Mine, a forgotten mission and a lost city somewhere in the Santa Catalina Mountains, north of Tucson, Arizona, has lured prospectors and treasure hunters for hundreds of years. The discoveries of early Spanish placer mining sites, stone ruins, and stories of the mountains only fueled speculation about the riches still left behind. Common knowledge among the locals eventually gained legendary status. Even more surprising was the abundance in gold, silver, and copper etched into the mountains. These stories became embedded in Arizona’s early history and were spun into some sensational legends and featured in numerous literary and film adventures. "Treasures of the Santa Catalina Mountains" explores the legends and history of the Catalinas, compiled from out-of-print books, magazines, newspapers and recollections from local prospectors. More than 430 pages and over 1,200 references.
