|SUMMARY - Mawson Plateau traverse|
|Start||Mt Shanahan - northern tip of plateau where Granite Creek meets Hamilton Creek. Dropped off by heli-charter from Arkaroola.|
|Mountain Ranges||Mawson Plateau and broader Northern Flinders Ranges|
|Pastoral Stations||Mt Freeling Station; Arkaroola Wilderness Sanctuary|
Almost all the dirt roads across outback SA were closed in the days after the March deluge, and many had to be graded to be reopened. This kept grader operators busy, so the runway at Moolowatana Station, the first station and servicable runway north of the Mawson Plateau, was still damaged. So like last year, we had to charter a helicopter to drop us out. More expensive, but being able to drop us almost anywhere it saved us two days walking in from Moolowatana Station.
The plateau spans an area seven kilometres wide and 30 kilometres long. The area is littered with large areas of exposed granite, capturing water in numerous rockholes. Granite Creek and its many tributaries drain the plateau, flowing to the north to meet Hamilton Creek before making their way out to Lake Callabonna - one of the many large salt lakes that form a horseshoe around the Northern Flinders Ranges. Its highest point is Freeling Heights, a bluff on the south-western corner of the plateau. Originally the plateau was named Freeling Heights, but was later renamed in honour of Douglas Mawson.The plateau is largely untouched, it's quite hard to find any sign of human impact. There are no roads or tracks, no buildings or fences, quite possibly no weeds (I've heard tell, I'm no expert), and little impact from feral animals, even goats (which are rampant in the Gammon Ranges to the south.) We found a couple of stardropper stakes in a clearing on our way up to Freeling Heights, marking the site of a government photo survey of vegetation. On stardroppers, one of the waterholes on upper Granite Creek is called Star Dropper Waterhole, so named after the single stardropper there that marks a corner boundary of the Arkaroola and Mount Freeling pastoral leases. We knew of this waterhole, we had seen photos, but did not know its exact location as the pastoral lease boundaries are not usually shown on the topographic maps. We did, unbeknownst to us at the time, see the waterhole on our return from the summit of Freeling Heights. In the back corner of a photo of the waterhole the star dropper can clearly be seen!
A single old track makes a small incursion on the plateau just south west of Mt Shanahan, an old mining track, the type such as litters the Northern Flinders Ranges. Without maintenance these tracks suffer from washaways and soon become undriveable. This one stretched a few hundred metres onto the plateau. It's unusual to hike in the Flinders Ranges somewhere that no 4WD could possibly travel, or has ever travelled.
There were are few other signs of human impact. Behind a rock above the Tee Junction Waterhole, one of the few permanent waterholes on the plateau (after decent rains it is thought to last ten years or so) we found an emergency cache of food and essential items. You know the essential things one might need: coffee, chocolate, cigarettes, toilet paper. From the logbook it seems to have been first placed there by Reg Sprigg in 1987, and has been well stocked since, very little was out of date. As the permanent waterhole, and one of the few named ones, it is a popular spot with hikers to camp at. That said, there were few entries in the logbook, but that may be due to hikers, such as us, not knowing the cache was there; we stumbled upon it on our second night there.
A couple of old stone cairns built by surveyors mark summits, there is one on Mt Shanahan, a summit which seems remarkably insignificant, and on Freeling Heights. Towering drystone structures, they never cease to amaze me in how well the surveryors of old constructed them. The Freeling Heights one, like all good summit cairns, is complete with a logbook of sorts, in this case loose paper in an old jar. Of all the notes in there, and there were not many - it seems there was only one, sometimes two, visits each year. Some year had no visits. Tafe was a common visiting party - the outdoor education course - they also featured quite well in the cache at Tee Junction Waterhole. Up at the Freeling Heights summit there were several cleared campsites, perhaps most clearly noticable by the large slabs of stone that had been carefully positioned to form chairs and even side tables.
The March rains filled all the rockholes, even after seeing so many waterholes we did not grow tired of them. It's hard to imagine what hiking here might look like in drier times. The waterholes were often an obstruction, a few times we had to scramble around them, many times over and around them. There were upsides to this though, by lunchtime on the first day we were already swimming in a vast waterhole. Every day on the plateau featured a good swim.
On our second day we decided to leave Granite Creek, with its many obstructing waterholes. We followed a spurline for two kilometres up to the escarpment edge, from here we had dramatic views over the eastern plains and Lake Frome. Following the escarpment to the south west, the escarpment grew increasingly dramatic. We crossed back across the plateau, which was no easy navigation task, to Granite Creek and its rockholes.
The views from Freeling Heights were also dramatic, we had a very clear day, one of the clearest I have seen up there. We could easily see Mt Painter, which we climbed in 2011, and further south Benbonyathe Hill (2010), Mt McKinlay, Patawarta Hill (2009) - 110km away - and Rawnsley Bluff on Wilpena Pound - 180km away.
On the fourth day we hiked to the escarpment, dropping off 400 metres in elevation down a long spur line to a creek. From here we followed it downstream to the hot springs at Paralana. The days were all hot, and most sunny, and we often sought out the shade of trees, no matter how small. A Paralana Hot Springs we sat in the cool reeds beside the hot flowing spring water. It was here we saw our first people since leaving Arkaroola, a couple visiting the springs in their 4WD. An offer of a cold beer would have been nice. Alas, unrefreshed we hiked on in the hot sun.
We camped beside a waterhole every night, and it was only one night where we forewent a swim, in that case to preserve the water from contamination for drinking. Our last night was possibly the best swim, in Bararranna Waterhole. Here the creek was flowing and the waterhole large, it reminded me of some of the rocky vegetationless gorge waterholes in the Kimberley, it was enormous.
On the sixth day we sidled into Arkaroola, and showers, cool drinks, food and chairs. Ah the things you miss hey.
