Rivers winding their way through Brazil’s Amazon Rainforest appear as tan lines due to the sediments they carry. Visible in the upper part of the image is the Amazon River, the world’s largest river by waterflow. The city of Manaus can be seen near the confluence of the Negro and Solimões (Amazon) Rivers.
Visible cutting diagonally across the lower part of the image is the Madeira River, the Amazon’s biggest tributary, with a length of about 3,250 km (2,020 mi). Some haze can be seen in the lower right quadrant, mostly south of the river. This is caused by smoke from fires, one of which is visible in the full image. As the fire is located near an area of deforestation, it may have been set in order to clear land for grazing, planting crops or human habitation.
