Copper at the Crossroads

Arizona has been a leading copper producer for more than a century. But the metals market is volatile. Those years have been marked by cycles of fortune and failure and boom and bust.
Copper at the Crossroads is a 3-part radio documentary examining the past, present, and future of Arizona’s copper mining industry.
The series aired in 2011 on Tucson NPR station KUAZ-FM.
Executive Producer/Reporter: Mark Duggan
