Photo Gallery

Koranga Crater, a Pliocene-to-Holocene hydrothermal explosion vent complex, is located in the Morobe goldfields of the Owen Stanley Range at the eastern end of the New Guinea Highlands. The gold mineralization here prompted one of the world's last great gold rushes in 1922. A landslide and possible hydrothermal explosion in May 1967 from a vent at the upper right produced the fresh landslide deposits seen in this photo. The volcanic origin of this event is uncertain.
