Dangerous Minds has just posted an excellent piece on the infamous Black River Falls in Wisconsin. The bleak history of this mining town was profiled in a 1973 book Wisconsin Death Trip and then, later in 1999, an excellent documentary of the same name. Being an avid film buff at university at the time of release, I remember the piece as being quite a landmark. It's shot almost entirely in gorgeous black and white and features a haunting soundtrack.
Someone has uploaded the whole thing to YouTube and I've embedded it below. I'm not sure how long it'll be around so I'd recommend watching it sooner rather than later.
