Alien-Looking Places on Earth 3

The giant opencast mines of Rio Tinto create a surreal, almost lunar landscape. Its growth has consumed not only mountains and valleys but even entire villages, whose populations had to be resettled in specially built towns nearby. Named after the river which flows through the region-itself named for the reddish streaks that colour its water-Rio Tinto has become a landscape within a landscape. The river red water is highly acidic (pH 1.7—2.5) and rich in heavy metals.
