List of highest mountains of New Guinea
This list of highest mountains of New Guinea shows all mountains on the island of New Guinea that are at least 3750 m high and have a topographic prominence of 500 m or more. These c. 50 peaks are also the highest mountains of Australasia, where, outside New Guinea, the highest mountain is Aoraki / Mount Cook in New Zealand with a height of 3724 m.[1] A list of highest mountains of Oceania with the same limitations is almost identical, with the addition of the Hawaiian volcanoes of Mauna Kea (4205 m) and Mauna Loa (4169 m) in 18th and 20th positions. The list also shows the 36 highest thus defined mountains of Indonesia, except for the 3805 m high Gunung Kerinci on Sumatra (#29 in Indonesia), and the 16 highest mountains of Papua New Guinea.
Limited topographical data
Many mountains in New Guinea are poorly surveyed and some major summits remain unnamed on maps. Even well measured mountains have conflicting heights on otherwise authoritative maps. For example, the highest point in Oceania, Carstensz Pyramid, was established to be 4884 m in 1973 when an Australian survey expedition put a beacon on the summit. This corresponded closely to the 4866 m estimate by the first Lorentsz Expedition in 1910 using repeated theodolite observations from the south coast. However, over time the mountain had grown in stature: measurements from northern observation peaks for the highest summit (each time Ngga Pulu) were 5000 m in 1910 by Ludolph Doorman and 5030 m in 1926 by Charles C.F.M. Le Roux.[2] The 1936 Carstensz Expedition using barometric and boiling point measurements on the summit of Ngga Pulu also derived an elevation of 5030 m.[3] After ascending the Pyramid in 1962, Heinrich Harrer even estimated that peak to be 17,096 feet or 5211 m high.[4] The 1973 survey established that the 1936 barometric estimates were consistently between 118 and 127 m too high. Nevertheless, the 5030 m height is still prevalent in most atlases and maps.[5]
Disappearing and disappeared glaciers of the Snowy Mountains
All mountains in West Papua are in the Maoke Mountains, a translation of the name “Sneeuwgebergte” or Snowy Mountains endowed to them in 1623 by Jan Carstensz, at which time many of the peaks indeed were covered by extensive ice caps. By the beginning of the 20th century, at least five such glaciated regions remained on the highest mountains. In 1913, the 4520–4550 m high Prins Hendrik-top (now Puncak Yamin) was named and reported to have some "eternal" snow.[6] The ice cap of Wilhelmina Peaks vanished between 1939 and 1963, while the Mandala / Juliana ice cap disappeared in the 1990s.[7] The Idenburg glacier on Ngga Pilimsit dried up in 2003, leaving currently only the remnants of the glaciers on Mount Carstensz, which are expected to disappear before 2050 [8] and perhaps as soon as 2015.[9] The snow melt on the last mountain has caused a change of the highest summit of New Guinea: somewhere between 1936 and 1973 the title of highest summit of Oceania changed from Ngga Pulu, the highest point of the Northwall Firn (now split into West and East Northwall Firn), to the rocky spires of Carstensz Pyramid 3 km to its south-west.[10]
The list
The list contains some unranked summits that are either of general interest, may show topographic prominences of >500 m given better data, or are more than 12 km isolated from any higher point.
Notes and references
- ^ Aoraki was 3764 m high until 14 December 1991, when a massive rock/ice collapse broke off 10 meters. Subsequent erosion of the exposed ice cap reduced its height by a further 30 m as of November 2013.[1]

- ^ Measured in 1975 at 4855 m (Anderson, p. 21), but its exposed spire is now also higher than the neighboring, melting Ngga Pulu
- ^ In 1936, the snow dome of Ngga Pulu seems to have been ca. 4900 m high and with that the highest summit in the Netherlands Indies and Oceania (Anderson p. 22). For this reason it became in 1963 the original bearer of the name Puntjak Sukarno and then Puntjak Djaja. However, snowmelt had lowered it to 4862 m by 1973 (Anderson, p. 22).
- ^ An alternative height of 4640 m is inconsistent with 4720 m SRTM-contour lines around the summit.
- ^ a b On some maps and in some sources the Jayawijaya / Orange range represents the eastern half of the Nassau range (from the 3475 m Jila Pass at 4°5′36″S 137°40′16″E / 4.09333°S 137.67111°E to the Baliem gorge). The original Orange range is then often considered part of the Star mountains, the eastern section of the Jayawijaya range, or has the name Wisnumurti Range.
- ^ Highest SRTM-contour lines are 4680 m.
- ^ Probable location; alternatively the highest of the three Idenburg Peaks, climbed by Harrer and company in 1962, is 1.8 km to the ESE at 04°2′42″S 137°4′21″E / 4.04500°S 137.07250°E.
- ^ a b The names of the Valentijn and Jan Pietersz Coen mountains are switched on different maps, sometimes JPC, sometimes Valentijn being northwest and having the highest summit of ca. 4500 m.
- ^ a b One of multiple summits on a ridge with the same highest contour lines.
- ^ A mountain originally named after the son of Charles Darwin. The height of Mt Ubia is usually given as 4234 m. This probably was the 1910 theodolite measurement from the south coast of the top of the spectacular, 1500m-high south wall. The true summit 2 km NE would have been out of view.
- ^ This summit is unnamed on most maps, but is called Mount Gladstone on the 1942 American Army Map, on which it is estimated to be only 11,400 feet (c. 3475 m) high.
- ^ Also Mt Salawaket or Mt Saruwaged and Sturmkoppe. Mt Bangeta may alternatively refer to a 4060 m subsidiary peak at 6°16′42″S 147°03′12″E / 6.27833°S 147.05333°E.
- ^ Sometimes reported with an SRTM-data incompatible 4350 m height.
- ^ The height of Antares, always considered the highest mountain of the Sterrengebergte (Star mountains), has been all over the map. The first ascendants underestimated it by some 300 m to be 3650 m [4] while the height of 4170 m on many maps appears 200 m too high. The highest (very narrow) SRTM-contours around the summit are 3940 m.
- ^ The commonly reported height of 4,360 m appears 400 m off target.

- ^ Other sources (e.g. Paul W Williams, Arête and Pinnacle Karst of Mount Kaijende, 2009) seem to indicate that the name "Mount Kaijende" belongs to the ca. 3500 m high mountain 10 km to the east at 05°29′40″S 143°17′28″E / 5.49444°S 143.29111°E.
- ^ The 3774 m height is reported for Mount Bedego, which could match the 3700 m contour lines at this location, which more often bears the name Mount Undan or Mount Udon.
- ^ The highest point of the Weyland mountains for many years was held to be 3891 m, but this is not born out by maximum SRTM-contours of 3720 m.
- ^ A pointy peak which may well be over 3750 m high despite SRTM-contours of only 3700 m.
