Mt Kosciuszko, New South Wales, Australia.
Notes: At 2,228 metres (7,310 ft) above sea level, Mt Kosciuszko is mainland Australia's tallest mountain. Located on the Main Range of the Snowy Mountains in Kosciuszko National Park, the mountain is part of the Australian Alps National Parks and Reserves in New South Wales.
Mt Kosciuszko and the Snowy Mountains were formed by two geologic uplifts caused by convection in the Earth's mantle (one about 100 million years ago and another 50 million years later). The landscape has also been shaped by prolonged periods of faulting, folding and erosion.
We took the trail from Thredbo in Autumn, 2016, following along the gridded walkway. The landscape peeled back as we got higher. Defined by treeless ridges of hardy granitic rocks and deep valleys etched by streams, pointed intrusions crown the peak of the Kosciuszko Mountain. Just below, Lake Cootapatamba, formed by a glacial action scraping a contour in the native rockface, cups water from rain and snow.
