How large an area does the mountain range that contains Mount Feathertop comprise?
Australian Alps The Australian Alps, an interim Australian bioregion, is the highest mountain range in Australia. This range is located in southeastern Australia, and it straddles eastern Victoria, southeastern New South Wales, and the Australian Capital Territory. The Australian Alps contain Australia's only peaks exceeding 2000 m in elevation above sea level. The Alps are the only bioregion on the Australian mainland in which deep snow falls annually. The Alps comprise an area of 1232981 ha .
Columbia Mountains The Columbia Mountains are a group of mountain ranges along the upper Columbia River in southeastern British Columbia, and also in Montana, Idaho and Washington. The mountain range covers 135,952 km² (52,491 sq mi). The range is bounded by the Rocky Mountain Trench on the east, and the Kootenay River on the south; their western boundary is the edge of the Interior Plateau. Seventy-five percent of the range is located in Canada and the remaining twenty-five percent in the United States; American geographic classifications place the Columbia Mountains as part of the Rocky Mountains complex, but this designation does not apply in Canada (despite a British Columbia government tourism campaign to rebrand their southern portion as the "Kootenay Rockies"). Mount Sir Sandford is the highest mountain in the range, reaching 3519 m .
