Having travelled out to the Blue Mountains a couple of times there were a few things that interested me for which I didn’t immediately have answers; so I did a little research …..
Why are they blue?
The Blue Mountains is densely populated by oil bearing Eucalyptus trees which fill the atmosphere with finely dispersed droplets of oil, this, in combination with dust particles and water vapour, scatter short-wave length rays of light which are predominantly blue in colour.
Who first crossed the mountains and when?
Gregory Blaxland, William Charles Wentworth, and Lieutenant Lawson were the first Europeans to cross the Blue Mountains which they did in 1813.
They departed on the 11th May and completed their journey eighteen days later on the 29th May 1813.
When was the first road built?
In 1814, William Cox assembled a team of thirty convicts and eight guards to build a road across the Blue Mountains. Starting at Emu Plains on the 18th July 1814, in just four months the team had completed a road covering a distance of 47 miles to Mount York. In just six months, Cox had crossed the Blue Mountains with a road of one hundred and one miles all the way to Bathurst. (The Bathurst Road).
In the current way of doing things “research” means having a look on the internet. Therefore I have included a number of links so that you can read further if you wish, just click on the graphics below:
