The Weyland Mountains, also known as the Kobowre Mountains, are a mountain range in Western New Guinea. The Weyland Mountains are the westernmost mountains in New Guinea's Central Range, which extends eastwards to the island's southeastern tip.[3]
The Weyland Mountains include several high peaks reaching up to 3891 metres elevation. They are surrounded by lower-elevation areas.[1] To the west, a low pass only 160 metres in elevation separates the Weylands from the highlands of the Bird's Neck Isthmus and New Guinea's western peninsulas.[3] On the north and south, they descend to New Guinea's northern and southern lowlands. To the east, a valley containing the Paniai Lakes, Paniai, Tigi, and Tage, also known as the Wissel Lakes, separates the Weyland Mountains from the Snow Mountains, or Sudirman Mountains, further east.[1]
The Weyland Mountains Nature Reserve, also known as Pegunungan Wayland Nature Reserve, protects the central portion of the range. It has an area of 2230.0 km2.[2] Enarotali Nature Reserve covers the eastern end of the range.
