While Mia was in school, Nancy and I took Copper Queen Mine Tour. On the way downtown, we passed the Copper Prince Mine which is now closed. We ate lunch at Jimmy's, known for their Chicago specialties of hot dogs and Italian beef sandwiches.
Bisbee was founded as a copper, gold, and silver mining town in 1880, and named in honor of Judge DeWitt Bisbee, one of the financial backers of the adjacent Copper Queen Mine. The mining operation was taken over by Phelps Dodge Corporation until 1975 when they halted its Bisbee copper-mining operations.
To compensate for the economic loss due to the end of the mining era, the city in cooperation with Phelps Dodge implemented a tour of the world-famous mine. Volunteers cleared tons of fallen rock and re-timbered the old workings. The Queen Mine Tour was officially opened to visitors in 1976. More than a million visitors, from all 50 states and more than 30 countries, have taken the underground mine tour train.
