Owen Stanley Range is the south-eastern part of the central mountain-chain in
Papua New Guinea. It was seen in 1849 by Captain
Owen Stanley while surveying the south coast of Papua and named after him. Strictly, the eastern extremity of the range is
Mount Victoria , which was climbed by Sir
William Macgregor in 1888, and it extends as far west as Mount Thynne and Lilley. But the name is generally used to denote the whole of the chain of the
Papuan Peninsula, from Mount Chapman to the south-eastern end of the island, and to include
Mount Albert Edward which is really separated from it by the Wharton Chain.
