The Big Stack
Standing tall since 1919, the Big Stack is visible long before you arrive in Anaconda. At 585 feet high it was the country's tallest smokestack; the Washington Monument could fit inside it. For decades it benevolently belched lead and arsenic over the town, but smelting operations ceased in 1980 and in 1983 the stack was condemned for demolition. Proud Anacondans banded together and saved the stack. It's now a Montana State Park -- but it's a park you can't visit, since the dirt surrounding the Big Stack is still so toxic that you're kept over a mile away.
