^ Thanks Mr Turbo. That is a favourite of mine too.
Ok, Day 13 continues...
Travelling with a hammock easily sets you up for one of the true luxuries of travel in the bush: a nap after lunch. Instead of getting hot and tired during the hottest part of the day one can rejuvenate while zoning out to be only half tuned in to the sounds of the bush. In this instance, the occasional twenty eight parrot and mulga parrot, a few honeyeaters, and the inevitable raven punctuated my half sleep, while fortunately very few flies interrupted my relaxation. The trickle of a nearby creek brought with it the occasional waft of moist cool air in the shade.
Revived, I set off for an afternoon of exploration, and the first stop was the nearby Kolay Mirica Falls.
The most impressive feature of the Gawler Ranges is its age. Once you understand just how old these ranges are, you begin to appreciate the geography in a different way.
1592 million years is very old rock. It is estimated that some 1600 million years ago, animal, plant and fungi kingdoms had first split. It was about 700 million years before arthropods (organisms with jointed feet such as trilobites, spiders, crabs) developed from chordates (organisms with spines), and hundreds of millions of years before the first fossils. It was about 1000 million years before the super-continent of Gondwana, which comprised all land on earth, began to split into smaller continents, conciding roughly with what is known as the Cambrian explosion.

Another way to appreciate the age of the rocks of the Gawler Ranges is to consider that they are over a tenth of the estimated age of the universe (13.7 billion years). They are as old as the approximate period of time that it will take the Fremantle Dockers to win an AFL premiership, and for the Mitsubishi Outlander to evolve into something resembling an off-road vehicle. On current estimates, their age in years is slightly less than the odds against the Labor Party winning the next federal election in Australia, but only about one thousandth of the number of dollars of the U.S. national debt. ($14.71 trillion as at 9 September 2011).
25,000 square kilometres, the estimated size of the lava flow from the eruptions that made these ranges is about the size Vermont in the USA.
Figures like that make the rocks look different…
One would hardly expect to find waterfalls among the spinifex fringed hills and rhyolite outcrops, particularly at this end of summer. There was however a surprising amount of evidence of recent water, and new growth caused by generous rains over the Australian interior from the previous winter which was followed by summer storms.
Moving on from Kolay Mirica, I headed towards Pondannna outstation, encountering Eureka Bluff (431m) along the way. Bearing in mind the age of the geology, this was obviously once much bigger, and the valleys which now appear as plains were once much deeper. I was in fact driving on rocks that were once part of the ranges. It reminded me of how Uluru is sedimentary rock formed from the Musgrave and Petermann Ranges, which in turn were once part of perhaps the highest mountain range on the planet: higher than the Himalayas are now. (Incidentally, Uluru as a formation is only about a fifth of the age of these rocks).
The afternoon was getting on, and I passed through a number of gullies in the vicinity of Pondanna outstation. Approaching Conical Hill, the track rose significantly, and the torque of the H6 made the rocky climb much easier than a 2.5 litre boxer would have done. Wash-aways from summer rains were obvious
Nearing the top, a Myall tree in flower further demonstrated the abundance of recent rains.
It is easy to see how the early pastoralists, as in so much of the arid interior, would have been fooled that the land could support sustained agriculture. One gets the illusion that the rolling hills and valley go on forever.
(another obligatory sign…)
I got back behind the wheel, and took in the view for a little longer through the windscreen before continuing on the track. This was really a rewarding moment. Such a view, a magnificent afternoon, a great vehicle and the promise of cold beer in camp. I had seen no-one since the two gentlemen I had seen back at Kolay Hut, and had seen no-one else since leaving Kimba. You feel privileged at times like this, as though nature has turned on the show just for you.
Destination: Kododo Hill,
There wasn’t much time for photography of any quality as the shadow of the hill I was camped at crawled up Kododo Hill (413m) to the east of me, but the view itself was spectacular. Gazing at that range, the colours changing and shapes appearing to shift is a sight and experience I will remember for a long time. It is a truly special place.
Once I got dinner out of the way, I relaxed for the evening with a brilliant star-filled sky, and wondered which of the stars and galaxies before me were 1592 million light years away…
