These stamps continue the Australian Antarctic Territory Landscapes series which began with the iceberg issue in 2011. The mountains and mountain ranges featured reveal the beauty and grandeur of the landscape.
Antarctica is the highest continent on earth and Mt McClintock, in the eastern sector of the AAT is its highest mountain. Although elevations in excess of 4,000 metres exist in the western sector of the AAT, these are ice domes and generally not considered mountains, but the definition is frequently debated.
Mt Parsons near Mawson Base is one of the most regularly ascended peaks due to the repeater installed on its summit. The repeater facilitates communications on VHF band between field parties back to station around the area. Mt Parsons rises more than 1,000 metres above sea level.
The Mawson Escarpment is flat-topped and faces west extending for more than 100 kilometres. It was discovered by Flying Officer J. Seaton of the Australia National Antarctic Research Expeditions in 1956 and named after Sir Douglas Mawson. The South Masson Range was discovered and named by BANZARE and mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition in 1936-37.
The David Range is part of the Framnes Mountains. It was sighted and named in February 1931 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson.
