Columnar Rocks in Australia

[Big Red]

As far as i can work out, these are the spots in Aus that have the Hexagonal Shaped Rocks.

How columnar structures are created

During the cooling of a thick lava flow it contracts, the lava can shrink vertically without fracturing but will fracture with horizontal contraction. It is this multiple fracturing, or network fracturing, that results in the formation of columns. The resultant column is a polygon and can vary in shape from 3 to 12 sides.

14-8-15: FINGAL HEAD northern NSW

Headed down to Fingal Head and camped the night so I could get an early start for pics, Ron was planning on meeting me around dawn.
I took a few night pics of Tweed Heads across the Tweed River.




I headed in to a remote carpark to wait for first light.
It was a fairly dark dawn in the canopy so dawn was well under way before I woke up then just as i had started grabbing my gear out Ron rang to see where I was, he had park in another carpark and had already walked up to the headland.


I hastily headed down to the beach and turned north to the headland as the colour faded from the sky


The sky had lost its colour by the time I got to the Lighthouse.


I met up with Ron and we headed to the cliff edge to wait for the Sun to rise and bring some colour back.
The sun peeked its head over the horizon lighting up Cook Island and the Basalt Headland.


Looking over the headland on to the small temporary island we could see the tide was quite high with water rushing through the channel between it and the mainland




We climbed down closer to the small causeway to wait to see if there was a break in the waves rolling through the channel




The sun was lighting up the mainland cliff face as we waited


The waves were exploding over the causeway making the rocks quite slippery.




The lone fisherman on the other side decided to head back while he still could using his special shoes to get enough grip to scramble across the wet rocks in the small window of time between the exploding waves.


Ron and I climbed back to the top of the headland as the sun lit up the beach along the beach to the north.


we spotted several Dolphins swimming south past us so we followed them to the other end of the headland.


Occasionally they would surf under the waves


We walked back up past the Lighthouse with quite a difference in the sky making a much better pic.


The light turned off in the Lighthouse as we headed off for home.


Was another great morning, thanks for keeping me company Ron

2-4-22: SAWN ROCKS, Mount Kaputar National Park, New South Wales


Friday 2nd April – Good Friday
Heading towards Narribri I stopped at The Sawn Rocks and walked up for some Photos, those amazing shaped rocks just hanging there 40 metres up makes me wonder how often they fall … and they do as witnessed by the large and small Hexagon and Pentagon shaped rocks and clumps in the creek below.

19-7-16: ORGAN PIPES Gawler national park SA


We drove on down into the Gawler Ranges visiting the sights at the top end of the park, the Organ Pipes gave an indication of a lot of the top end sights with the sticks of rock featuring in most of the park, we stopped at Stone Dam which had a man made dam above a waterfall and internet access!
