Happy Places 2: Tasmania’s Central Plateau

The Central Plateau has been dubbed ‘the roof of Tasmania’, and ‘the land of a thousand lakes’; which is about as nuanced as calling Australia the ‘wide brown land’. There’s so much more to this wild and high part of our island state. 

 

It owes a great deal of its identity to dolerite, and to a massive sub-surface upwelling of that igneous rock during the Jurassic age. Almost equally its identity has since been shaped by the ice sheet that covered the surface during a number of glacial phases. That covering was more ‘doona’ than ‘sheet’, as it measured hundreds of metres thick in some parts. As that huge amount of ice, at least 6000 sq km in area, slowly jostled and crunched across the plateau, it carved out lakes – many more than a thousand – and left sharp peaks and dramatic clefts.

 While much of that ice-age drama is over, the Central Plateau remains a vast area of largely wild high country. It’s roughly bounded by Great Lake to the east, the Great Western Tiers to the north, and the Walls of Jerusalem to the west. To the south the boundary is more vague, but perhaps the Lyell Highway marks a convenient edge. As this post is about my ‘happy places’, it’s probably okay to leave the big picture fuzzy, and focus in on the subject at hand. 

 

So … where on this cold, high, wet and wild plateau are my happy places? I’m particularly thinking of smultronställe, a Swedish word that evokes that sweet, semi-secret favourite place; somewhere that – particularly during these cold months – makes me smile just thinking about it.



[A sweet end to a lakeside night]

 During more than 40 years of walking in Tasmania, I’ve been privileged to walk across the plateau numerous times, from every direction. I’ve written about some earlier walks here Walking With Ada and here No Lack of Lakes  All that plateau wandering makes choosing particular smultronställe as difficult as naming my favourite child. But if I had to pick just three Central Plateau ‘happy places’, they would be (in no particular order):

 

1.     The Walls of Jerusalem

2.     Mount Rogoona

3.     Un-named Lakes and Pencil Pine Groves

 

1) Certainly this choice needs some narrowing down, as The Walls of Jerusalem National Park covers 518 square km! Scattered across this mountain-fringed park are some wonderful campsites, both formal and informal; on-track and off-track. And I could have selected any of those. But because mountains are such a feature of The Walls, I’ve chosen Solomons Throne as my Walls of Jerusalem ‘happy place’. 



[Friends share special times on Solomons Throne]

The peak is not the highest in the park, nor is it the most difficult to ascend. What make it sit so sweetly in my memory is a combination of my experiences here, and the superb vistas from the top. I’ve been up there in thick snow, and relished views outward towards a snow-bound Overland Track, and inward to the nearby pine-fringed lakes and vales. I’ve been there with family, introducing them to the wonders of our wilds. I’ve been there with friends (many times); with first-time walkers; and with international visitors who thought Australia didn’t have mountains. While I will certainly tire during the steep climb up a rocky chute to the peak, I will never tire of sitting on the Throne.

2) The upper Mersey River roughly marks one edge of the Central Plateau. The Mersey Forest Rd also gives good access to one of the sweetest spots on the western side of the plateau: Mount Rogoona. I first heard about this mountain during the 1980s. A group I walked with had been planning a trip there, but a major fire burned out much of the track and surrounding areas, so we walked elsewhere. It wasn’t until nearly 20 years later that I finally reached that peak.



[Mount Rogoona from Lake Myrtle]

And what a peak! It sits, sphinx-like, above the waters of Lake Myrtle, its knobby summit giving way to dolerite cliffs that are like a younger, smaller sibling of the Organ Pipes of kunanyi/Mt Wellington. For most visits to Rogoona, Lake Myrtle is the most convenient camping spot. However direct access to the peak is not easy from the lake. I found this out – in reverse – when a few of us decided to return from the summit direct to the lake. I would not recommend it! Rather the track between Lake Myrtle and Lake Meston leads to an easier slant-wise route to the mountain.



[Summit Views from Mount Rogoona]

Rogoona is essentially a small plateau whose summit is near the sheer dolerite cliffs on its north-western edge. So the views from the top are as vast as they are stunning. Steeply beneath and quite nearby is the tranquil Lake Myrtle. But your eye soon wanders west beyond the lake, over the nearby Cathedral Plateau, to the highest mountains of Tasmania, from Mt Pelion East to Mt Ossa and numerous others further south. 

 

Not once, but twice I’ve had that view ‘interrupted’ by a wedge-tailed eagle flying over. I’ve written in more detail here Eagle, but suffice it to say that being buzzed and eye-balled by the largest raptor in Australia is one of the greatest privileges of being in remote Tasmania. 



[Close encounter with the Rogoona Eagle]

After you’ve had that kind of mind-bending, time-stretching summit visit, there are few better places to sit and contemplate it than by the shores of Lake Myrtle. I’ve written about one particular experience here Myrtle 1, here Myrtle 2, and here Myrtle 3.


3) If the preceding ‘happy places’ would be easy to locate, the third is deliberately vague. Un-named Lakes and Pencil Pine Groves is a category of smultronställe that invites you to do your own explorations; make your own discoveries. And there could be few better places to wander in search of lakes and pencil pine groves than the Central Plateau. 

 

I once started the eye-watering job of trying to count the number of lakes just on the 1:25 000 Ada map. I gave up after counting 350 in one typical 10 sq km strip. Given there were 19 such strips still to count, it’d be fair to estimate between 5 000 and 7 000 lakes on the Ada map alone.



[So many lakes! A small part of the Central Plateau]


Obviously the number of lakes alone makes searching the plateau for sweet spots a lifelong task. But once the search begins, it becomes more subtle than you’d think. Lakes mean water, and many lakes mean a lot of water. That in turn means often waterlogged ground, and camping in such places isn’t much fun – not to mention the impacts it can have on that environment. In my Central Plateau wanderings I’ve seen many spots that looked great from a distance, but turned out to be unsuitably sodden once you got there and looked for tent spots. 

 

Happy Place searchers also have to consider another weather factor apart from precipitation, and that’s wind. The often fierce winds here further narrow your camping options. What may be a perfect site on a calm night can turn perilous when the wind gets up. Shelter is paramount, which is why pencil pines are often your friend. But there are complications here too. Many pencil pine groves are so dense that there’s no room for tents. And if there is room, the ground is often covered in dense, soggy sphagnum and/or gnarled tree roots. 



[Boots off and relaxing at a secret campsite]

 So … have I found some ‘Goldilocks Zone’ campsites on the Central Plateau? Of course I have. And I’ve spent some of my most blissful days and nights between a lake and some pencil pines. Am I going to share their locations here? Sorry, I’m not. What I can say is that if you haven’t searched for your own version, then you have a baffling, frustrating, but ultimately sublime quest ahead of you. If you have found such sites - or you recognise some of the ones pictured - I’d suggest you share that information sparingly. Let others have the thrill of the quest. Some places just shouldn’t be on Instagram.

Thoughts from the Overland Track: Part 1 - Mt Pelion East

[part 1 of a series of reflections on a November walk through Tasmania's Overland Track]


Mt Ossa and the rest of the Pelion Range from the slopes of Mt Pelion East

Pelion Gap, at an altitude of 1126 metres, is the high point of day 4 on the Overland Track. It is a place more exposed than most to the wild weathers that made, and continue to make, this high and rugged area what it is. My rule of thumb that there is always snow in November in the highlands holds true today. Showers turn to flurries of sago snow as we sag down at the Gap.

Its been a constant hour and a half trudge up from the Pelion Plains, but the promise of fresh bread from a friendly commercial guide has drawn us on. We top the bread with homemade raspberry jam, cheese and other delicacies. The heavenly taste brings internal sunshine even as the next snow shower swoops over the Gap.

Four members of the group think better of our earlier plan to climb Mt Pelion East. That leaves three of us to don extra layers, including gloves and overpants, before we continue up the mountain. Ive been here twice before, but it is hard to resist the short, sharp ascent up what looks an impossibly steep summit ridge.

My hazy recollection, that you walk straight towards the nipple-shaped summit before skirting left then ascending from that side, proves accurate for once. But as we start to clamber up the final steep band of dolerite, sago snow engulfs the mountain and us. We shelter behind some pillars, the sago piling up like tiny styro-foam pellets at our feet. We are in no danger. This is a half-hearted sprinkling of snow that will melt within the hour. But it does make me wonder what it would have been like here 12 000 years ago, during the last Ice Age.

Waiting out the snow showers, Mt Pelion East


Back then the confetti of snow at our feet would have been several hundred metres thick. And we would have been waiting a couple of thousand years for it to melt, giving the slowly flowing snow and ice ample time to grind away the bulk of Pelion East. The peak itself is a nunatak, meaning it stayed largely above the deep snow. But its flanks, exactly where we are standing, would have been buried deep. The brutal and relentless mass of ice would have gouged away most of the mountain side. Later that day we will find glacial erratics large boulders carried and dropped by the moving ice peppered throughout the Pinestone Valley.

I am sobered by the thought that Aboriginal Tasmanians were here during that whole age. Without the likes of boots, down jackets, Gore-Tex, polar fleece or ruck-sacks, and carrying only fire and essential tools, they ranged throughout this whole area, leaving their own erratics in the form of quarries, middens and all manner of other artefacts. The Pelion Plains and similar open buttongrass areas are probably the largest artefacts of all: the result of aeons of systematic Aboriginal burning.

The snow soon stops, and we scramble the final few dozen metres to the summit. Tim is in his element, reminded of foul-weather scrambling during his years in Scotland. Rose, from the Netherlands, is just thrilled to be in such a wild and elevated place.

From the summit we can see for a hundred kilometres or more in every direction. Across Pelion Gap is Mt Ossa, the states highest peak. For a short while the snow showers have cleared its bulky eminence, as they have the other mountains of the Pelion Range: Mt Pelion West, Mt Thetis and Paddys Nut. The wind too has dropped, and it looks like we will have at least five minutes to enjoy the summit before the next shower. On a day like today that is more than we could have asked.
