An expedition in 1971, sponsored by the National Geographic Society, pinpointed Carruhasanta Creek, which runs off the north slope of Mount Mismi in southern Peru, as the source of the river.This location became widely accepted in the scientific community and remained so until the mid-1990s—although a Polish expedition in 1983 contended that the source of the river was actually another stream, nearby Global Positioning System (GPS) technology in the 1990s, researchers again attempted to navigate the entire length of the Amazon.The Francisco de Orellana, who gave the river its name after reporting pitched battles with tribes of female warriors, whom he likened to the Amazons of Greek mythology.Although the name Amazon is conventionally employed for the entire river, in Peruvian and Brazilian nomenclature it properly is applied only to sections of it.The Amazon basin is a great structural depression, a subsidence trough that has been filling with immense quantities of sediment of Cenozoic age (i.e., dating from about the past 65 million years).This depression, which flares out to its greatest dimension in the Amazon’s upper reaches, lies between two old and relatively low crystalline plateaus, the rugged Brazilian Highlands (lying somewhat farther from the main river) to the south.The team then proceeded to measure the river’s length.As part of this process, they had to determine from which of the Amazon’s three main outlets to the sea to begin the measurement—the Northern or Southern channels, which flow north of Marajó Island, or Breves Channel, which flows southward around the western edge of the island to join the Pará River estuary along the southern coast of the island.

Although considered a part of Amazonia by the Brazilian government and in popular usage, it is technically a separate system.This immense volume of fresh water dilutes the ocean’s saltiness for more than 100 miles (160 km) from shore..More than two-thirds of the basin is covered by an immense rainforest, which grades into dry forest and savanna on the higher northern and southern margins and into montane forest in the Andes to the west.The Amazon Rainforest, which represents about half of the Earth’s remaining rainforest, also constitutes its single largest reserve of biological resources.Since the later decades of the 20th century, the Amazon basin has attracted international attention because human activities have increasingly threatened the equilibrium of the forest’s highly complex ecology.
