Igarapé do Aturiá, Rio Negro, Brasil
Brazil, Amazonas, Comunidade do Aturiá
The Igarapé do Aturiá is one of the many forest streams that feeds into the Rio Negro. As the rainy season advances and the Rio Negro level rises, this clear igarapé wides as it starts to get invaded by the incredibly dark and tannin rich water.
What used to be the forest floor gets covered by leaf litter and a myriad of botanicals, fallen trees and branches create slower current areas and where the fine white sand of the bottom of the igarapé is exposed to the sunlight lush carpets of Eleocharis sp. grow.
