I tried to show two of Sebastiano Salgado's photos of the Serra Pelada gold mine - same place, one more close up - as a story, but can't seem to link them that way.
If interested, go to
http://www.masters-of-photography.com/, click on Salgado, click on the slides until you get to the Serra Pelada gold mine ones, and click on the slides in this order - #2, #3, #1.
Heck, I can't even get that to work. So, start out by googling Masters of Photography, and carry on from there.
(I saw these, or prints of these, at the Art Institute in Chicago during the 2006 a2k meet there.)
