The Quiz: What is the Duluth Complex?
A A rock formation
B A shopping center
C A psychological condition
The Boundary Waters Canoe Area Wilderness is located on the Duluth Complex, a mass of intrusive rock in northeast Minnesota. For many years, there has been a dispute over mining the 4 billion tons of copper and nickel ore within the complex, in an area just west of Boundary Waters. In recent years, a 20-year ban on mining was imposed to give time to study the potential effects of the mine. That ban was then overturned and is now potentially on the table again. Even more recently, some mining leases have been canceled, which may have sealed the deal on the mine’s future.
The correct answer to this quiz is A rock formation.
