Lake Rotopounamu (also known as Greenstone Lake, from the Māori roto (lake) and pounamu (greenstone)[1]) is a secluded lake in the Pihanga Scenic Reserve, in the Tongariro National Park in New Zealand's Central North Island.[2] It lies at the northwest foot of Mt Pihanga, and was formed by a landslide around 10,000 years ago.[1] The lake is fed by seven streams, but has no visible surface outflow. It is believed to drain underground.[1]
