Context paragraphs:
Alpine Club classification of the Eastern Alps: The Alpine Club classification of the Eastern Alps (German: "Alpenvereinseinteilung der Ostalpen" , AVE) is a common division of the Eastern Alps into 75 mountain ranges, based on the Moriggl Classification (ME) first published in 1924 by the German and Austrian Alpine Club.  The present-day division established for the German-speaking world (less Switzerland) was compiled by the German, Austrian and South Tyrol Alpine Clubs and published in 1984 and is also used for the basic numbering of Alpine Club maps for mountaineering.

Kosciusko Alpine Club: Kosciusko Alpine Club (KAC) is the second oldest ski club in Australia after the Kiandra Pioneer Ski Club (1861).  It was founded in 1909, two months after the NSW Government opened the Hotel Kosciusko at Diggers Creek, the first hotel in the Kosciusko area.  The Hotel Kosciusko became the winter home of KAC until 1930 when the Kosciusko Chalet opened at Charlotte’s Pass.  KAC was the only ski club in the Kosciuszko area until 1920 when the Ski Club of Australia was formed.

Section (Alpine club): The section (German: "Sektion" ) of an Alpine club (or that of any such Alpine society or association) is an independent club or society that, together with the other sections, forms the main organisation ("Alpine club").  Membership of an Alpine club is normally only possible through membership of a section.  The task of an Alpine club section is the maintenance of tradition and culture, the Alpine training of its members, the planning and implementation of mountain tours and expeditions, and also the maintenance of huts and trails in the mountains.  Many sections own Alpine club huts.  After the initial task of the Alpine clubs - i.e. the development of the Alps for tourism and Alpinism, was considered as largely completed in Central Europe today, the work of the sections moved increasingly into the service sector, including the organization of Alpine courses and tours as well as sponsoring climbing gyms.

Snowy Mountains: The Snowy Mountains, known informally as "The Snowies", is an IBRA subregion and the highest mountain range on the continent of mainland Australia.  It contains the Australian mainland's highest mountain, Mount Kosciuszko, which reaches to a height of 2228 m above sea level.  The range also contains the five highest peaks on the Australian mainland (including Mount Kosciuszko), all of which are above 2100 m .  They are located in southern New South Wales and are part of the larger Australian Alps and Great Dividing Range.  Unusual for Australia, the mountain range experiences large natural snowfalls every winter.  Snow normally falls the most during June, July and early August.  Therefore, most of the snow usually melts by late spring.  The Tasmanian highlands makes up the other (major) alpine region present in Australia.

Lake Albina Ski Lodge: Lake Albina Ski Lodge was built overlooking Lake Albina in the Kosciuszko National Park of Australia, by The Ski Tourers Association, (later renamed The Australian Alpine Club).  In 1952 the first Albina Summer Slalom Cup was held, taking advantage of the seasonally unusual snow conditions.  Summer time ski events continued for at least another 3 years on either Mount Kosciuszko or Mount Townsend.  The National Parks and Wildlife Service (NPWS) required the club to vacate the lodge in 1969, and it gradually became a ruin.  It was finally demolished by NPWS in 1983 .

Bergverlag Rother: Bergverlag Rother is a German publisher with its headquarters in Oberhaching, Upper Bavaria.  Since 1950 the company, that formerly went under the name of "Bergverlag Rudolf Rother", has published the Alpine Club Guides in cooperation with the German Alpine Club (DAV), the Austrian Alpine Club (ÖAV) and the South Tyrol Alpine Club.

Rappensee Hut: The Rappensee Hut (German: "Rappenseehütte" ) is an Alpine Club hut belonging to the Allgäu-Kempten Section of the German Alpine Club.  With 304 bedspaces it is the largest of all the 327 huts of the German Alpine Club.  It received a record number of guests on 19 September 1970 with 681 people overnighting.  On average the hut has about 15,000 overnight stays per year.

Australian Alps Walking Track: The Australian Alps Walking Track is a long distance walking trail through the alpine areas of Victoria, New South Wales and ACT.  It is 655 km long, starting at Walhalla, Victoria and running through to Tharwa, ACT near Canberra.  The track weaves mainly through Australian national parks, such as Alpine National Park and Kosciuszko National Park, though it is not exclusively restricted to national parks.  It ascends many peaks including Mount Kosciuszko, Mount Bogong, and Bimberi Peak, the highest points in N.S.W., Victoria, and the A.C.T. respectively.  The AAWT crosses exposed high plains including the Victorian Bogong High Plains and the Main Range in NSW.  To walk the whole trail can take between 5 and 8 weeks.  Food drops or a support crew are necessary, as the trail passes through no towns, although it passes close to the ski resorts of Mt Hotham, Falls Creek, Mt Baw Baw, Thredbo, Charlotte Pass and Perisher.

Charlotte Pass, New South Wales: Charlotte Pass (often erroneously referred to as Charlotte's Pass), elevation 1837 m , is a location, snow resort and village in the Snowy Mountains of New South Wales, Australia.  The pass is located in the Kosciuszko National Park where the Kosciuszko Road crosses Kangaroo Ridge.  Charlotte Pass is the closest village to Mount Kosciuszko.

Australian Alpine Club: The Australian Alpine Club was founded in 1950 and is one of the oldest continually existing Alpine clubs in Australia.  it was founded in 1950 by Charles Anton.  Huts were constructed in the "backcountry" close to Mount Kosciusko, including Kunama Hut, which opened for the 1953 season.  A rope tow was installed on Mount Northcote at the site and opened in 1954.  The site proved excellent for speed skiing, but the hut was destroyed in an avalanche, which also killed one person, in 1956.
