od vertical terrain. Construction began in 1957. Today, Thredbo has 14 ski-lifts and possesses Australia's longest ski resort run, the 5.9 km from Karel's T-Bar to Friday Flat; Australia's greatest vertical drop of 672m; and the highest lifted point in Australia at 2037m
The last establishment of a major skifield in NSW came with the development of Mount Blue Cow in the 1980s. In 1987 the Swiss designed Skitube Alpine Railway opened to deliver skiers from Bullocks Flat, on the Alpine Way, to Perisher Valley and to Blue Cow, which also opened in 1987. The operators of Blue Cow purchased Guthega in 1991, and the new combined resort later merged with Perisher-Smiggins to become the largest ski resort in the Southern Hemisphere. In 2009 Perisher had 48 lifts covering 1,245 hectares and four village base areas: Perisher Valley, Blue Cow, Smiggin Holes and Guthega.
Snowy Mountains Scheme
The Snowy Mountains also feed the Murrumbidgee and Murray rivers from the Tooma River, Whites River and Yarrangobilly River. The range is perhaps best known for the Snowy Mountains Scheme, a project to dam the Snowy River, providing both water for irrigation and hydroelectricity.
The project began in 1949 employing a hundred thousand men, two-thirds of whom came from thirty other countries during the post-World War II years. Socially this project symbolises a period during which Australia became an ethnic "melting pot" of the twentieth century but which also changed Australia's character and increased its appreciation for a wide range of cultural diversity.
The Scheme built several temporary towns for its construction workers, several of which have become permanent: Cabramurra (the highest town in Australia); and Khancoban. Additionally, the economy of Cooma has been sustained by the Scheme. Townships at Adaminaby, Jindabyne and Talbingo were inundated by the construction of Lakes Eucumbene, Jindabyne and Talbingo.
