Australia’s Blue Mountains, located just west of Sydney.
Formation of The Blue Mountains
Archaeological studies indicate that the Blue Mountains were formed around one million (1,000,000) years ago as part of the Kosciusko Uplift during the Pilocene Epoch.
Pressure from the east raised the area upwards in a monoclonal fold, reaching an elevation of around one thousand four hundred (1,400) meters to the top of the Blue Mountains where Mount Victoria is today.
Naming of The Blue Mountains
In 1788 the Blue Mountains were originally named “Carmarthen Hills” by Governor Phillip. However, it wasn’t long after that the distinctive blue haze surrounding the area saw the change in name to the Blue Mountains.
The Blue Mountains is densely populated by oil bearing Eucalyptus trees. The atmosphere is filled with finely dispersed droplets of oil, in combination with dust particles and water vapor and scattered short-wave length rays of light which are predominantly blue in colour.
The Blue Mountains Today
Just west of Katoomba the remains of a Eucalyptus tree can be seen with marks by the famous explorers Blaxland, Lawson and Wentworth. The Marked Tree, along with Caley’s Repulse at Lawson, are the only remaining marks of the early explorers. A cairn of stones was also placed at Linden. However, it is not certain if the existing cairn at Linden is the original.
