History
The escarpment or scarp was created, it is believed, between 225 to 280 million years ago and since eroded by creeks to its present height around 30 million years ago. Most of it is sandstone, with many Hawkesbury Sandstone boulders and ledges visible in addition to the actual cliffs. Its maximum heights are reached in the south, west of Albion Park at Knights Hill, 709 metres above sea level, and Mount Murray, 768 metres above sea level. This forms the eastern edge of the Southern Highlands plateau, uplifted along with the Blue Mountains around 70 million years ago.
Many of the towns on the coastal plain adjacent to the escarpment were first founded to harvest the cedar trees on the slopes of the escarpment or the coal seams beneath it. With the original logging industry of the area came the need for passes over the escarpment, creating such ones as Rixons Pass, Bulli Pass, O'Briens Road and Macquarie Pass. The city of Wollongong is the central city in the Illawarra.

Famous quotes containing the word history:
“The history is always the same the product is always different and the history interests more than the product. More, that is, more. Yes. But if the product was not different the history which is the same would not be more interesting.”
—Gertrude Stein (1874–1946)
“What has history to do with me? Mine is the first and only world! I want to report how I find the world. What others have told me about the world is a very small and incidental part of my experience. I have to judge the world, to measure things.”
—Ludwig Wittgenstein (1889–1951)
“What would we not give for some great poem to read now, which would be in harmony with the scenery,—for if men read aright, methinks they would never read anything but poems. No history nor philosophy can supply their place.”
—Henry David Thoreau (1817–1862)
