We are now on the Rio Negro, which is the largest blackwater river in the World. The dark color comes from humic acid, from incomplete breakdown of phenol-containing vegetation from sandy clearings. The Rio Negro flows into the Rio Solimões to form the Amazon River below Manaus, Brazil. We will continue our way to Manaus, Amazon, Brazil.
