Geography
The mountain is located in the western part of the Sudirman ridge, in the extreme west of the Maoka Mountains, 3.5 km north-east of Mount Jaya , 0.6 km north-west of Mount Ngga Pulu [2] , 2.4 km north from Mount East Carstens . Height - 4870 m. Relative height - 350 m; therefore, the mountain is not an independent peak, but belongs to the Jaya massif [3] . Sumantri is one of Indonesia's highest non-self-reliant mountains. In absolute height, the mountain is second only to Jaya.
Title
Until 1973, the mountain was known as the “Northwest Ngga Pulu”. In 1936, members of the Carstens expedition called Mount "Second Peak of the North Wall." Heinrich Garrer named the peak of Ngapalu, plotting it on a map compiled in 1962, while the western peak of Ngga-Pulu is “Sunday Peak” [4] . Describing his ascent to both peaks, Dick Isherwood used the name Ngga-Pulu for the peak, which is now called Sumantri, and Sunday Peak for the peak, which is now known as Ngga-Pulu [5] . The Indonesian government renamed the peak in honor of Professor Sumantri Bradyonegoro , Minister of Energy and Mineral Resources of Indonesia, after his death in 1973 [6] .
History
The southeastern peak of Ngga-Pulu was conquered by a Dutch expedition in 1936. The northeastern summit was first conquered in February 1962 by an expedition led by the Austrian mountain climber Heinrich Garrer .
Alone, the Northeast Peak was first conquered by the Italian mountaineer Reingold Messner on September 27, 1971. A year later, Leo Murray, Jack Baines and Dick Isherwood climbed the peaks of Ngga-Pula and found the stake that Messner left on the second top of the "North Wall", which they called Ngga-Polo now - Sumantry [5] .
Geology and Glaciology
The mountains of the Central Range of New Guinea, which include the Maoke Mountains and in particular Mount Sumantry, are formed and continue to form as a result of the collision of the Australian and Pacific plates, as a result of these processes the height of the mountains increases. The upper part of the mountain is composed mainly of limestone . [7]
