A miner rests on top of a rustic sluice-like contraption layered with pieces of carpets to capture the gold deposits from water sediment in La Pampa in Peru's Madre de Dios region. Engine noise is the characteristic sound of this Amazonian jungle territory. There are no trees, only hills of moved earth and artificial ponds of brown water where gold is mined.
