The Star Mountains (Dutch (colonial): Sterrengebergte; Indonesian: Pegunungan Bintang) are a mountain range in western Papua New Guinea and the eastern end of Highland Papua, Indonesia, stretching from the eastern end of Indonesia to the Hindenburg Range in Papua New Guinea.

Mountain ranges Pegunungan Bintang Regency in Indonesia and Star Mountains Rural LLG in Papua New Guinea are part of this mountain range.

History

The earlier Western expedition to the mountains was led by Jan Sneep, a Dutch colonial civil servant who operated from the Sibil Valley. The expedition, which started in April 1959, mapped the terrain and collected anthropological data of the people who lived in the area. The expedition used two small Bell helicopters, but the altitudes severely limited their effectiveness and one of them crashed, forcing the expedition to rely more on traditional man power. Climbers from the expedition reached the peak of Puncak Mandala on 9 September 1959.

Climate

The Star Mountains have an annual rainfall of more than 10,000 mm/year, and although no official scientific weather station has ever been established it has been claimed to be one of the wettest places on earth.
