In 2011, scientists found something unexpected hiding beneath the Amazon. There, 4,000 meters (13,100 feet) beneath the earth was an enormous body of water almost long enough to rival the Amazon and much wider.

River Hamza, as Brazil’s National Observatory unofficially named the beast, acts like drainage for the region and was discovered after Petrobras (an oil company) drilled hundreds of wells. They were drilled back in the 70s and 80s, but when scientists later took a look inside they discovered the monstrous waterway that was hiding underneath. It was after the leader of this team of researchers that the underground waterway was named.

It begins under the Andes in the Acre region and winds its way on through to the Solimões, Amazonas and Marajó basins before slipping out unseen into the Atlantic Ocean. The flowing river Amazon speeds along at around 5 meters (16 feet) per second. By comparison, the painfully slow-trickling Hamza moves along at a casual 1 millimeter (0.04 inches) per hour, writes The Guardian.

Dead end, panacea, or something in between?
