The Forgotten River is located in northern Fiordland, New Zealand in Mount Aspiring National Park, and is a tributary of the Olivine River. The Forgotten River starts at the Forgotten River Col at the western edge of the Olivine Ice Plateau in the Five Finger Range. It flows south-westward to join the Olivine River as a hanging valley south of Four Brothers Pass. [1] [2]
