Brazilian scientists believe they have located an underground river an estimated 4,000 meters below the Amazon River.

Named after the head of the research team that located the river, the Hamza River stretches an estimated 6,000 kilometers, emptying deep in the Atlantic Ocean.

Like its famous above ground counterpart, the underground river is believed to flow from west to east, but at a much slower pace than the Amazon.

Scientists recently said they believe the Hamza River may explain the low salinity of the Amazon.

Brazil's National Observatory hopes to confirm the existence of the river in the next several years.
