Rio Tinto, Spain( ganso.org )
The waters of the Rio Tinto, Spanish for "painted river," are an eerie and beautiful reddish brown, but the real story behind the rich colors is not so pretty.
Since ancient times, the river area has been a site of mining activity for its valuable copper, iron, silver and gold; metal runoff from the mines has long contaminated the river, and dissolved iron gives the waters its red color.
