1813 crossing of the Blue Mountains

The 1813 crossing of the Blue Mountains was the expedition led by Gregory Blaxland, William Lawson and William Charles Wentworth, which became the first successful crossing of the Blue Mountains in New South Wales by European settlers. The crossing enabled the settlers to access and use the land west of the mountains for farming, and made possible the establishment of Australia's first inland settlement at Bathurst.^[3]
