The photos yesterday of the gold mining in the Congo, Men Who Moil for Gold, reminded me of the Amazonian gold rush in the early 1980's where at Serra Pelada a mountain was leveled and then turned into a 100 metre deep pit by hand. The photographer Sebastião Salgado made his name with images from this mine. There was a documentary made of this gold rush but I can not find it. Maybe the other mining fans know the name of it. Here is a long (90 minutes) discussion of his work from the Berkeley Graduate School of Journalism.
