DescriptionMount Kaputar National Park, Narrabri, NSW. Sawn-rocks 01.jpg
English: Sawn Rocks is a 40m high wall of organ-pipe formations, resulting from volcanoc activity. The pale sections are revealed after long pentagon shaped tubes have fallen into the creek below.
The forty (40) metre high towering wall of pentagonal basalt pipes is the sheered off remains of a basalt lava flow from the Nandewar Volcano which dominated the area 21 million years ago. While this type of five-sided (pentagonal) ‘organ piping’ is not rare to lava flows. it is exceptionally rare to find them so perfectly formed and preserved and is recognised as being one of the best examples of columnar jointing in Australia.
