Geography
The length of the ridge is about 370 km, and the average height of the peaks is 4000-4500 m. The highest peak is Mount Punchak-Mandala (4760 m), the second highest mountain is Yaamin (Prince Hendrik), 4540 m high. Jayavidzhaya is an eastern ridge Maoka Mountains, in the Central Highlands, in the area of the Indonesian part of New Guinea Island. In the west, the ridge passes into the Sudirman ridge, in the east - into the Star mountains.
In 1997, in the mountains, animals were seen that corresponded to the description of extinct Australian Tasmanian wolves - tilacin [2] .
The Digul , Pulau , Taritatu rivers (the right tributary of the Mamberamo ) and Bali , the left tributary of the upper reaches of the Sepik River [3], originate in the mountains.

Glaciers
The highest massif of the ridge, Mount Punchak-Mandala, has remained stable ice cover since 1989, which in 2003 completely melted [4] .
Geology
The mountain range belongs to the relatively young Pacific Alpine folding belt. The mountains were formed and their height continues to grow, due to tectonic processes, which are caused by the movement of the Australian plate to the northeast, and its contact with the Pacific plate , which in turn dives under the Australian edge. The Maoka tectonic microplate, which is usually associated with the Australian Plate and located on the border of collisions with the Pacific Plate, is also the foundation for the Maoka Mountains, including the Jayavijaya Range [5] .
