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 4,072 metres (13,360 ft), 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 from Mount Chapman 3,376 metres (11,076 ft) to the south-eastern end of the island, and to include Mount Albert Edward 3,990 m (13,091 ft) which is really separated from it by the Wharton Chain.
Vehicular roads, though not impossible, would be very difficult and expensive to construct. In fact one was constructed during World War II crossing from Wau in the north to Bulldog in the south and known as the Bulldog track. It was largely due to the impossibility of transporting heavy equipment across the range that the Japanese failed to secure Port Moresby as a base early in 1942. The mountains are rough and precipitous, with occasional fertile plateaux which are occupied by native food-gardens.
