Archaeological studies indicate that the Blue Mountains were formed around one million years ago as part of the Kosciusko Uplift during the Pliocene Epoch.
Pressure from the east raised the area upwards in a monoclinal fold, reaching an elevation of around three thousand feet to the top of the Blue Mountains where Mount Victoria is today.
In 1788 the Blue Mountains were originally named "Carmarthen Hills" and "Landsdowne 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, which, in combination with dust particles and water vapour, scatter short-wave length rays of light which are predominantly blue in colour.
