"The Anaconda Smelter Stack was constructed in 1919, as part of a massive copper smelting operation. It is 585 ft tall, making it, according to some, the tallest freestanding masonry, and perhaps the largest, in the world. It is also situated on a hill and is visible from miles around, including from I-90 between Deer Lodge and Butte. In fact, the Washington Monument (at 555 ft) would easily fit inside this towering smoke stack! A strange and amazing monument to industrialism, when viewed in conjunction with Butte's Berkely Pit, gives an idea of the scale of the mining operations that once dominated this part of the country." - Steven Perez from Bookmarklet
