The Jayawijaya Mountains, formerly known as the Orange Range, are the eastern mountain range of the Maoke Mountains in the central highlands region of the Indonesian part of New Guinea. The range extends for 230 miles east of the Sudirman Range to the Star Mountains. Its highest point is Trikora Peak at 4,750 meters (15,580 feet). The Baliem River has its source in the range.
Inhabitants of the range include the Ketengban.[1]
In 1997 sightings of animals matching the description of the thylacine, an extinct Australian marsupial were reported from "the Jayawijaya region of Irian Jaya".[2]
