Background
The Greater Blue Mountains Area consists of 1.03 million hectares of sandstone plateaux, escarpments and gorges dominated by temperate eucalypt forest. UNESCO says its eight protected areas show the evolution and diversification of the eucalypts in post-Gondwana isolation, with 91 eucalypt taxa, ten percent of Australia's vascular flora and relict species such as the Wollemi pine surviving in tiny refuges.
The blue comes from eucalyptus oil evaporating in the heat and scattering the light. Not mountains in the usual sense but a deeply cut plateau, from under 100 m to 1,300 m, it lies 60 to 180 km inland from Sydney and takes in seven national parks and the Jenolan Caves. Wikivoyage says Katoomba, 1,017 m up, was home to the Gundungurra and Darug peoples, who called it kedumba, shining falling water, and became a resort town in the early 20th century, with art deco shopfronts to show for it.
