At 585 feet tall, "the Stack" at Anaconda Smoke Stack State Park is a solid reminder of the important role the Anaconda Copper Company played in the area's development. Built in 1919, the stack, one of the tallest freestanding brick structures in the world, is listed on the National Register of Historic Places. Smelting operations ceased in 1980. There's a viewing and interpretive area with displays and historical information, but you cannot access the smokestack itself.
