It was going to be a hot day with the temperature settled at 32 C early in the day so we stayed around camp in the shade catching up with our books and watching other campers pack up and leave wondering where the next destination might be. We decided to stay another two nights in Narrabri as we had yet to see one of the main attractions of the area, the Sawn Rocks in Mt Kaputar National Park.
From Narrabri, – where we are camping for the next few days – 33 kilometres off the Newell Highway we turned into the parking area from where we walked into the rocks. The well irrigated land on either side of the road are the lush paddocks of a large grain research station that is part of Sydney University’s Plant Breeding Institute which I hope is not being funded to be engaged in genetically modifying grain.
From the information plaques I learned that these five-sided rocks were formed as basaltic lava flow cooled slowly and evenly allowing crystals in the molten rock to align perfectly. Vertical shrinkage cracks occurred at right angles to the cooling surface forming the five-sided columns (in the photo below there are also six-sided rocks).
We arrived back at camp hot, sticky and more than a little grumpy. The heat had sapped our energy and we headed to the local swimming baths to cool off and regain our sense of humour. Alas it was not to be. The outdoor pools do not open to the public until this weekend and the indoor pools were 29C and as noisy as can be expected during school holidays. Back to camp for cold showers and a cup of tea … there are few things not improved by a good brew of tea.
Thankfully the day finally cooled and we’re loving the breeze from across the creek. The weather man has promised cooler temperatures for tomorrow. I’m hoping he’s on the ball with his prediction.
