A Landsat-8 satellite image taken in April 2013 clearly shows the landscape disruption associated with mining activity, spanning an area over 11 miles long and up to 4 miles wide. Sediment-laden runoff in this area of high rainfall (it is a rainforest, after all) is rushing uncontrolled into adjacent rivers, coloring them pale muddy brown:
Measurement of the area impacted by mining; this does not include adjacent areas of deforestation (pale green) that probably indicate rapid settlement and farming accompanying the influx of miners. |
