Here's a bit of trivia that most of you probably didn't know, unless you've lived in Butte: Montana was once home to a real, old-fashioned roller coaster!
It was, of course, at the old Columbia Gardens amusement park outside of Butte. Established in the early years of the twentieth century by William A. Clark, the copper magnate, the Gardens was Butte's primary recreational venue for some seventy years; the author John Gunther called it a "threadbare little park," but it was all that Butte had. And threadbare or not, the roller coaster looks like it was pretty cool.
Columbia Gardens was acquired by the Anaconda company in 1928, and they kept the place going until 1973. In typical Butte fashion, the park's grand old carousel was destroyed in a mysterious fire that year, while the roller coaster and nearly everything else was torn down. The town has wanted to build a new Columbia Gardens ever since, but (again, in typical Butte fashion) the plans haven't gone anywhere.
Today, most of the old park site is beneath hundreds of feet of mine waste rock.
