Wallangarra Ridge: Girraween National Park

Wallangarra Ridge  is a little visited section of Girraween National Park in Queensland’s Granite Belt.  It is a spectacular landscape of   granite domes,  extensive rock slabs  and  giant balancing tors.  The dominant vegetation is a low Eucalypt woodland still showing the fire scars from 2019 bushfire season.  As the bulk of the walk is off-track , some navigation skills are needed.

Girraween means ‘ Place of Wildflowers ‘

The Wallangarra Ridge  sits at 1100 metres, while predictably cold in winter it was still quite warm during the day. Late March, 29 degrees centigrade. The  scrubby vegetation made long-sleeved shirts and  trousers a wise satorial option. 

The Parks website  provides this irresistible description of the Wallangarra Ridge : “…  breathtaking views sweep over to the Wallangarra township and distant rolling hills.  Soak up the vistas of nearby Mallee Ridge,  the giant monolith known as The Turtle  and Girraween’s  highest peak, the majestic  Mt Norman…On a hot afternoon,  cool breezes waft through the lush gullies between Mallee Ridge and Wallangara  Ridge .  Listen out for the rustling of bell-fruited mallee…You’ll soon forget the gruelling climb!

Geology

The geology of Girraween  is not particularly  complex.  The area is the remnant of a pluton of Stanthorpe Adamellite ( a quartz monzonite ), which is a major unit of the New England Batholith,  intruded  as a  molten  mass in the Early Triassic,  some 225 mya.

As the overlying rock was eroded the granite  mass expanded setting up stress fractures forming regular rectangular  joint patterns.   These rectangular  erosional jointlines had a strong influence  on the development of  Girraween’s  landforms.  Girraween’s domes, tors,  rock slabs and rectilinear drainage  pattern  are typical of granitic landform assemblages throughout the world.

Sunday

After a long five hour drive from the coast we pulled into the Park HQ on a pretty warmish afternoon. A hurried lunch and we were heading south on the Castle Rock-Mt Norman track, more uphill than I wanted. Neither my fellow hiker, John, nor I were keen to haul in water supplies for two days of walking and camping so the plan was collect some on the way to Wallangarra Ridge. Finding said water supply proved elusive as most gulleys and creek beds were dry,. Surprising given recent rains in a strong La Nina season . But a little bit of detective work and some scrub bashing unearthed a trickle hidden in a glade of ferns. Enough to provide an initial five litres each. Tomorrow we would have to replenish the supply. But our 1:25000 topo map showed nothing in the way of perennial streams in our intended camping zone. All we had to do now was to haul the additional five kilograms on the 250 m climb to the The Sphinx and then to the track terminus at The Turtle. From here it was all off-track.

Navigationally,  it was simply a matter of following our noses around the eastern cliff line of The Turtle and heading  SSW along the 1100 m contour line.  This involved a fair bit of bush-bashing and picking the easiest route between and around the large outcrops of granite.  To avoid too much bush-bashing, we took to open rock slabs whenever the opportunity arose.

By late afternoon, our enthusiasm waning, we propped at a rare flattish patch of sand nestled between rock slabs and boulders and relatively clear of burnt out scrub.  It was too late to go galivanting around looking for the Wallangarra Ridge Remote Campzone still some one and a half kilometres to our South-West and 100 metres down in a decidedly scrubby looking valley. I’m not sure why camping down there would offer any positives.

Our camp  nestled on  a rare patch of level sand.

After several cups of black tea to rehydrate,  we ferretted out all our warm gear, donning  trousers, thermals, fleece coats and beanies and wandered  out to take in a spectacular a  red sunset .

Our rocky  eyrie looked  out  over the Queensland /New South Wales township  of Wallangarra, some six kilometres to the  south.  In the far distance  was the Roberts Range, marking  the  boundary of Girraween’s  sister park, Sundown.

The Roberts  Range

The Roberts Range is a 1000 metre divide that separates the Severn River to the north from its southern neighbour, Tenterfield Creek.  Both are tributaries of the Dumaresq River.  It is named after Francis Edwards Roberts, the Queensland Government Surveyor who was involved in the 1863 border survey together with his New South Wales counterpart , Isaiah Rowland.   There are plans afoot to expand the Protected  Area Estate in the Granite Belt to include the Roberts Range area and help link Girraween and Sundown National Parks. Another concept under consideration is a Border Walking Trail along the easement of the Qld – NSW border.

Border Track. Roberts Range.
NSW – Qld Border Track on Roberts Range. Sundown NP.

This easement is a well maintained 4WD track that parallels the border fence, technically a Dog Check Fence.  The walk along the fenceline easement is a classic high range roller-coaster, up and down…up and down. A winter walk without parallel.  Believe me when I tell you that it is best avoided  over summer.  Read more about the Roberts Range walk at the end of this post.

Back on the Wallangara Ridge we had no campfire.   A cold WSW wind sent us scuttling off to our tents, lulled to sleep by forgettable podcasts and the occasional hooting of Boobook owls.

Monday

5.30 am . Rolled out to another crispy Granite Belt morning.  John was already up, cranking up the billy for our coffee followed by a substantial bowl of thick creamy porridge.  I my case, a tried and tested mixture of rolled oats, raw muesli, sultanas, plump dried apricots, shredded coconut and lashings of powdered milk. Fuelled up, we were up and running ( walking ) by 8.00 am.

Today was off-track to reach the high point of Wallangarra Ridge SSW of our campsite, as the crow flies.  If only we were crows.  We had read somewhere that the summit  is marked by a small rock cairn, from which we were promised extensive views across the park and down to Wallangarra township.

But first… find some water.  Our thought bubble of siphoning and filtering stagnant water from shallow pits and pans ( sometimes referred to as gnammas )  in the granite didn’t appeal.

Unappealing stagnant water in a shallow pan near our campsite.

But the gods smiled.   Several La Nina seasons meant that we should stumble across a trickle in nearby swales. Which we did.   In a swale no more than 500 metres downhill from our camp. Pretty unusual.

The swales are clothed in ‘Gully’ open woodland which develops in sheltered run-off situations I identified a few of the scorched dominants: Banksia spinulosa, a Callistemon , Eucalyptus brunnea and a dense regenerating understorey.

From the scrubby swale our line of travel took us out and up onto our morning tea vantage point where we propped in the shade at the top of a series of rock slabs stairs.  A short distance to the west  we could make out the highest part of Wallangarra Ridge .   John scanned along its skyline with his telephoto lens until he located a mini summit cairn.  Behind us and off to the north were easily the best views of The Sphinx and Turtle in the whole park.  

Twenty minutes later we stood on the summit boulder at about 1140 metres.  To our south was Bald Mountain ( 952 m ) and six kilometres in the distance was the border town of Wallangarra.

Wallangarra

Wallangarra is a small town of 500  0n the border of Qld and NSW.  It grew up close to the site a 1859 border survey marked tree, indicating the border between Qld and NSW. 

It is on Ngarabal country with Wallangarra  said to mean ‘ lagoon’.  I have read that wallan means water and guran means long. Long water as in billabong or lagoon.

Meanwhile, back on Wallangarra Ridge, we  drifted off northwards down the toe of the ridge in search of the mythical official  Wallangarra Ridge Remote Bush Camping Zone.  Unsucessfully.  After an hour of thrashing around in the dense regrowth in the vicinity of the GPS coordinates provided, we gave up. Anyway, there was no chance a slotting a tent in this stuff.  Bit of a navigational  mystery actually.  According to the Parks website … ” there is no defined camp site and access is via difficult cross country walking “.  We turned for home, intent on  finding enough water to see us through another day.

Water supply. Wallangarra Ridge. Girraween NP.
Lucky to find a supply of fresh water.

Back at the ranch we settled in for a decidedly leisurely and late lunch, several brews of hot black sweet tea and a nanna nap in the shade.  Though the latter was moveable feast as we searched for the deepest  shade.

Come late afternoon, John sloped off, camera on alert.  No doubt off to hunt down any unsuspecting Lyrebirds and Button Quail which he was convinced were scratching through the heaps of leaf litter.  Meanwhile I wandered around checking out all the nearby rock slabs hoping for anything of  geologic or botanic interest .

On a previous trip to Girraween we had been fortunate to see and hear Lyrebirds at nearby Mt Norman, so weren’t surprised to hear them again close to our campsite.

The Lyrebird is one of nature’s best mimics.  It can imitate a variety other bird species such as cockatoos, butcherbirds and whipbirds.  But it doesn’t draw the line at bird calls.  It can reproduce the sound of saws, guns and engines.

One Lyrebird story I read happened at a Victorian timber mill.  The mill used three blasts of a whistle to signify an accident and six blasts to notify a fatality.  One day the local Lyrebird blasted out six whistles, no doubt creating considerable workplace disruption. 

I have been tricked by  a Lyrebird mimicing the sound of a ‘reversing’ truck.   Our hikers’ camp in Sundown National Patk was hidden in  scrub with a small 4WD campround nearby.   The sound of a ‘reversing’ vehicle  at the 4WD campground attracted our attention as it had persisted for well over fifteen minutes.   I waddled up to check things out, thinking perhaps a 4WD had bogged or some such problem.  No vehicle in sight but the ‘reversing’ sound continued from the undergrowth.   The mystery of the phantom 4WD camper was solved.  Lyrebird.

Interestingly, scientists know that some mimicry is of now extinct species, passed on from parent to chick over the generations.

Another sunset worthy of the ABC TV weather report , a decent feed, a chin wag and it was all over for today. My Macpac micro green tent beckoned.

Tuesday

5.30 am.  Time to roll out into the pre-dawn twilight.  My pocket thermometer hovering on 10o C with a cool Southwester riffling across our campsite.  A bite to eat then we struck camp, packing our gear and leaving tents out to dry.

Our walk today was off to our east onto an unnamed adjacent ridge, aligned in the same NE/SW configuration as the Wallangarra Ridge. At 1220 metres it is nearly 100 metres higher than Wallangarra Ridge and more densely vegetated.   The attraction  was that from its summit we should be able to see across to the complex that makes up Mt Norman ( 1266 m ) and the Mallee Ridge ( 1230m ).  Maybe our Girraween sojourn for next year.

Summit of Wallaroo Ridge

Our line of travel took us initially over lower rock slabs then climbed into mature stringybark forest, habitat for a  Wallaroo, a large furry macropod,  which took off when we disturbed it.  We wound in and out of huge granite boulders before fetching up on a narrow summit plateau at 1200 metres.  Perched on the plateau were jumbles of huge tors topping out at over 1220 metres.  Naming rights… Wallaroo Ridge.

Wallaroo aka Euro

Our Wallaroo ( Osphranter robustus ) was, as the specific name implies ,  sturdy ( and shaggy-coated ) .  They are generally solitary and nocturnal.  The Eastern Wallaroo is not on the threatened species list and has an extensive territorial range in Australia’s Great Dividing Range.

We scrambled to  the top of the highest tor for morning tea.  Now we had impressive clear easterly views to the domes of Mallee Ridge and Mt Norman.   Mt Norman was named after Sir Henry Norman, Governor of Queensland from 1889 to 1895.   Getting to the Mallee Ridge and thence to Mt Norman from here looked like a hard slog.  Maybe one for the future.   Fortunately, there is an easier way,  from the Mt Norman track.   Although the twin domes ( 1230 m ) at the SW end of the ridge looked a tad formidable.  My Hema Girraween  map describes the walk as… ” easy rock slopes “.  I live in hope .

Bell-fruited Mallee & the Mallee Ridge

While  traversing the lower rock slabs, we had spotted a line of Bell-fruited Mallees growing in a jointline which had retained a bare minimum of mulch that was enough to sustain a viable pocket of Mallees.  These were the mallee Eucalyptus codoncarpa ,  that also grows on the nearby Mallee Ridge, and after which it was named.  In Girraween, the Bell-fruited Mallee is only found on Mt Norman and rocky outcrops to its west and south- west.  Despite its somewhat restricted distribution in Girraween it is listed on the IUCN Red List of Threatened Species as being of ‘least concern.’

Morning tea rest over, we backtracked to our campsite where we polished off our lunch leftovers and the inevitable mug of tea.  With a final check of the campsite, we hoisted up the monkeys and waddled  off for a leisurely afternoon’s walk back to our overnight camp at Bald Rock Creek campground.

One of the attractions of poking around offtrack is that little surprises form part of the experience.   This time we chanced on a high  ledge festooned  with a mass of rock orchids  and then futher on, an unusual find, a Bootlace Orchid.

The Black Bootlace Orchid

The Black Bootlace Orchid ( Erythrorchis cassythoides ) is a leafless climbing orchid. It has thin, dark brown to black stems that climb up to five metres up tree trunks.   It has displays of 10 to 30 yellow to green flowers.  Surprisingly, a Bootlace popped up in my suburban native garden in SEQ, lasted several years, then died back for no reason that I could figure out.

The Bootlace was first described by Richard Cunningham who sent his specimen and descriptive notes to his brother, the explorer Alan Cunningham.  Alan Cunningham forwarded the description on to the the English orchidologist, John Lindley.  Richard Cunningham had originally named it Dendrobium cassythoides but it was later renamed as E. cassythoides.

By 4.00 pm we were setting up for our final night in the civilised surrounds of Bald Rock Creek Campground. Although this had been a short visit to Girraween, we had explored a littled visited section of this outstanding granite park which I had always been keen to investigate. Coming up next year … the Mallee Ridge.

A description of one of my walks on the Roberts Range

The walk is the classic high range roller-coaster starting at 1067 metres, dipping and rising: 973 m, 1039 m, 1030m, 1015m, 1087m and reaching 1120m at our final climb before turning off and descending to the Sundown Road.

Roberts Range. Sundown NP

Climbing up to our first high point, Hill 1067 we passed into a special habitat, a high altitude forest, restricted to the very highest parts of Sundown and the Granite Belt. This is open forest, dominated by Silvertop Stringybark (Eucalyptus laevopinia), Yellow Box (E. melliodora) and the best name of all, Tenterfield Woollybutt (E. banksii). Silvertop Stringybark and Tenterfield Woollybutt are interesting in that they are disjunct populations of the same species growing further east at Lamington and Mt Barney. It is likely that they survive here on traprock because of the cooler, misty micro-climate on the highest points of the Roberts Range. Further along the range, on the summits of the highest hills at 1087 metres and 1120 metres, we passed through more small patches of high altitude forest.

As we climbed to the final high point at 1120 metres we entered a designated ‘essential’ habitat. These are areas meant for the protection of a species that is endangered or vulnerable. In this particular case the species was the Superb Lyrebird (Menura novaehollandiae) neither seen nor heard by our party. The Superb is the King of Karaoke and is such a good mimic that the bird being copied cannot tell the difference. The male Lyrebird has a repertoire of 20-25 other bird songs as well as mimicking car engines, chain saws and even barking dogs.

When Queensland was proclaimed a separate colony on 6th June 1859, Surveyors Roberts from Queensland and Rowland from New South Wales were sent to define the boundary between Queensland and New South Wales from Point Danger to the Dumaresq River. They started work in 1865 and worked separately using their own instruments. As their traverse lines were different the defined border appeared in different positions. Ultimately the Roberts survey was accepted and this was the line depicted on our map and that we were following today. I was keen to find any relics of their traverses such as rock cairns or horse-shoe blazes on trees. I found one old blaze, indecipherable, so there is no evidence that it was part of the border survey. It would be interesting to do the entire Roberts Range traverse with data from Robert’s original field book.

Old Survey Blaze on Qld – NSW Border.

Roberts, an Irishman, trained as an engineer and in 1856 he became surveyor of roads for the Moreton Bay District later gaining a post as a surveyor with Queensland’s Surveyor-General’s Department in 1862. Colonial surveyors were tough, capable bushmen able to endure considerable hardship: life under canvas, poor food, heat, flies, arduous travel and isolation. Unsurprisingly, it was a constant struggle to stay healthy. Queensland colonial surveyors could be struck down by any number of health hazards: Barcoo Rot, Bung Blight, Sandy Blight, Dengue Fever, Malaria, snakes and crocs. Francis Roberts escaped all these only to die prematurely of sunstroke in 1867, aged 41.

Today, the border is marked by a Dog Check Fence; an outlier of the mighty 5,412 kilometre Dog Fence that runs from Jimbour in Queensland to the Great Australian Bight in South Australia. The Dog Fence is said to be two and a half times the length of the Great Wall of China and is easily visible from space. Our 1.8 metre high Dog Check Fence or Dingo Fence is a relic of an intricate maze of some 48,000 kilometres of interconnecting vermin fences built to keep dingoes and bunnies at bay. Unsuccessfully.

Girraween National Park has long been one of my favourite bushwalking haunts. Its springtime wildflower displays, rugged granite landscapes and frosty climes make for superb walking adventures. Nestled in the western section of the park, abutting the QLD-NSW border is what I consider the best of Girraween: spectacular granite domes rising to over 1200 metres, extensive swamps, creeks cascading down smooth rock slabs, wildflowers in profusion, and always the possibility of sighting a Superb Lyrebird, or perhaps a solitary dingo, or maybe, just on dusk, a wombat trundling across creek flats.

The name Girraween, “place of flowers” dates back to the 1960’s when a public naming competition was held for the enlarged national park (11,800 hectares). A prize of $50.00 was offered and the winning name was “Girraween”. Disappointingly, it is not a word in a local aboriginal dialect, even though a number of aboriginal groups appear to have lived in and travelled through the area: the Kambuwal, Jakamabal, Kwiambal, Ngarabal and the Gidabal. The Stanthorpe district was thought to have been on a significant trade route from the western plains to the east coast, and on a north-south pathway to the Bunya festivals in South East Queensland. The Park info centre displays a few aboriginal artefacts collected locally including axe heads, grinding stones and even a stone implement that had been bartered from remote Papua New Guinea. Thankfully, several place names in Girraween are aboriginal in origin and some are retained on maps: Bookookoorara Creek, for example, is said to refer to the noise made by a possum and the original name for The Pyramids was Terrawambella, changed, regrettably, to the more prosaic The Domes in 1902, and finally The Pyramids in 1920.

Sunday: Castle Rock Campground to Racecourse Creek: 11 kms.

And so, on a warmish Sunday afternoon at the tail end of September, six walkers, Sam Rowe, Peter Fowler, Brian Manuel, Eva Zacher-Maj, Joe Kirkpatrick, and their worthy leader, yours truly, set off on the first leg of their 58 kilometre walk through the backblocks of Girraween National Park. Today’s 11 kilometres would take us to our overnight campsite on Racecourse Creek; but not before stashing supplies for a final night BBQ bacchanal at Castle Rock Campground. Several of my walking companions, who should know better, were foxed by the early start to spring and had strategically downsized to lighter sleeping bags and coats. Meanwhile, Peter and I ditched our rain gear, gambling on the Bureau of Meterology’s promised forecast of fine weather until week’s end.

The easy part of the afternoon was walking the tourist track to Mt Norman. But once on the flanks of the mountain I imprudently let Peter convince me that crawling through a 50 centimetre wide crack between massive vertical sheets of granite would be a cool bushwalking thing to do. Speleologists would call it ‘a squeeze’. For the svelte Sam, trim Eva and even the lean and hungry Peter, this was no drama. But for the three somewhat pudged-up and ageing track dogs, getting irretrievably wedged was a distinct possibility. Predictably my size 12 Rossi boots got stuck. Comrade Rowe’s suggestion that I should re-arrange my feet ballerina style was a stretched tendon too far. But all in all, it was, as Peter predicted, great fun.

Life in the Fowler fast lane careered on. Peter, Brian and Sam took leave from their more cautious companions and shimmied up a rock slab, teetered along a dodgy looking ledge, hauled up on a sapling and then disappeared from view, heading for Mt Norman’s summit (1267 m). Some half hour later three bottoms appeared and my friends gingerly lowered themselves one by one onto said ledge. To my considerable relief.

As the sun dipped low to the western horizon we beetled off to find an overnight campsite. On dusk, the sun gone, and the temperature plummeting, we settled into a bush camp on Racecourse Creek where it flows between Twin Peaks and Billy Goat Hill. To my knowledge the only billy goats around were the two-legged variety, minus their down jackets and minus warm sleeping bags.

Monday: Racecourse Ck Camp To South Bald Rock via West Bald Rock: 14.2 kms.

After an early morning jaunt up Billy Goat Hill (1118 m) to defrost (1°C), we shouldered our 15 kilogram monkeys and headed south, following Racecourse Creek upstream towards the Roberts Range and the QLD-NSW border. This was gaiter central. We puddled along, winding in and out of creek-side thickets and ducking to and fro across the swamp’s edge. Slow progress this. But like all decisive leaders, I had “a” solution. Brian “The Bulldozer” Manuel was recalled to a temporary leadership role and pressed into service at the front, pushing his way through the dense whipstick re-growth. This is precisely why we keep Brian on the payroll. Strangely, no-one challenged him for pole position. So, with his conga line of five walkers now in tow, Brian led us up Racecourse Creek, executed a hard left hand turn out of the boulder and thicket -choked creek bed and finally stepped out onto the West Bald Rock fire trail. Not before Eva’s leg tangled with a deep bog-hole in the swamp. But, as I discovered, Eva is a walker of considerable tenacity and she strode on, without complaint, for the remaining 47 kilometres nursing a bruised shin and a wonky knee.

A pre-lunch climb led us to the summit of West Bald Rock (1210 m), rewarding us with hazy views across to our destination for today (South Bald Rock) and on the morrow (Bald Rock in NSW). And then the highlight of the whole trip. Brian and I wanted to re-locate a nearby border cairn which, it is claimed, had been erected by Surveyor Roberts in the 1860’s during his survey to fix the QLD-NSW border. Brian had stumbled on it years ago and he and I were keen to find it again, although I had suspicions about the commitment of our fellow amateur historians to this venture. Despite the warm conditions we padded off across sheets of granite and through belts of scrub, heading about one kilometre to the south. With a bit of fancy bush navigation and some black magic from Joe and his GPS we found a fully intact survey cairn (Roberts No 1375), just where Brian predicted. Bill Kitson and Judith McKay’s tome Surveying Queensland 1839-1945 has an excellent chapter on Queensland border surveys as well as a photo of  the cairn.

An afternoon of relaxed pootling along slashed fire trails past Middle Bald Rock delivered us to our campsite under the towering slabs of South Bald Rock. This is an outstanding bush campsite: ample shade, flat tent pads and clear running water in nearby Dingo Swamp. No dingoes, neither seen nor heard .But what was this… horror of all horrors… a campfires prohibited sign. How will Brian, Peter and Joe possibly survive? Fuel stove only tonight.

As the light faded Sam pointed out that the bright stars hanging in the western sky were, in fact, planets. The brightest, Venus, then Saturn and hanging low to the horizon Mercury. Near Mercury was a star, Spica.  On matters of astronomical trivia, on another late September eve in 1990, the Japanese astronomer Mr Tsutomu Seki of Comet Ikeya- Seki fame, discovered a new 4.7 kilometre diameter main-belt rocky asteroid. Naming rights were given to his friend and colleague in Australia, one Mr Kato who lived near Stanthorpe. Thus we have asteroid 15723 Girraween, named for Girraween National Park. A more detailed account of  asteroid Girraween can be found on the excellent website: www.rymich.com/girraween/.

Tuesday: South Bald Rock To Bald Rock Campsite: 14.35 kms.

Tuesday morning, warmer, a balmy 6°C, causing King Kookaburra, aka Brian, to bestir from his pea-pod yellow tent earlier than usual, soon after 4.30am according to one of my bleary-eyed informants. Conversely, a certain other party stubbornly refused to de-tent from his stately MSR pleasure dome until the more civilized hour of 6.00am. In any event we were still under way soon after 7.00am for the easy scramble up to the summit of South Bald Rock (1247 m).

South Bald Rock is the classic granite landform, a huge steep-sided domed mass of hard rock, technically referred to as an inselberg. Girraween lies at the northern end of the New England Batholith, an extensive plume of molten magma that cooled slowly deep below the earth’s surface, allowing the formation of rocks with large crystals, adamellite. Good for boot traction.  It is said that the Stanthorpe granites represent one of the most spectacular assemblages of granite landforms in Australia. For the geology buffs among you, an excellent and more detailed account of Girraween’s landscapes can be found in Warwick Willmott’s Rocks and Landscapes of the National Parks of Southern Queensland.

After descending South Bald Rock, we rounded up our now lighter monkeys and ambled off along the shady border trail towards Bald Rock. On this particularly enjoyable morning’s ramble through the shrubby open forest Peter sighted a Lyrebird scratching around in the leaf litter. The wildflowers were a kaleidoscope of colours: the pinks of Boronias, and Kunzeas; yellow Gomphlobiums and Donkey Orchids; red and yellow pea flowers, and absolutely stunning white and yellow sprays of flowering rock orchids, the mighty kings of the orchid world, Dendrobium speciosum. As the trail paralleled the border on occasion we played the game of stepping back and forth across the border, QLD-NSW-QLD-NSW-QLD.

Bald Rock Campsite, popular in school holidays, is operated by the NSW Parks Service and offers a well appointed camping ground: a shelter shed with BBQs, toilets, picnic tables, taps, dusty rock-hard tent pads and a big red TOTAL FIRE BAN sign which had Brian, Peter and Joe crying into their beers. Three cans of which Brian had somehow fandangled from a generous Victorian camper, another AFL tragic.

The main feature of the National Park is, of course, Bald Rock (1277 m), Boonoo Boonoo as it was known by local aborigines, meaning ‘big rock’. It is claimed to be the largest inselberg in Australia and also the Southern Hemisphere. We took the refurbished Bungoona Walk to the summit via the well manicured tourist track, only to be nearly blown off the top by a gusting 40 km/h westerly.

Wednesday: Bald Rock Campsite to Castle Rock Campsite: 17 kms.

Warm weather predicted (30°C) for our 17 kilometre walk back to Castle Rock Campsite. We followed the border trail initially, and then swung off-track to follow Paling Yard Creek northwards before fetching up at the Underground Stream (Bald Rock Creek) and the start of the tourist track. The walk back was relatively easy: traversing open granite slabs, across dry swamp meadows, down Paling Yard Creek and finally connecting with the system of 4WD management trails that led to the Underground Stream. Paling Yard Creek has some beautiful reaches where it riffles over sheets of granite, and trickles gently down cascades and over small waterfalls to fill tranquil pools below. We propped on one of these for morning tea.

As a finale, we could do no better than the Underground Stream. This is geologically interesting and well worth a visit. Here the creek has eroded swirling spa-like potholes deep into the granite bedrock. Below, a jumble of massive boulders has choked the creek; the water disappears from view, hence the ‘Underground Stream’. In times of low flow it is possible to climb down and through the boulders. Nearby granite slabs have been scored by dykes. These are usually narrow linear depressions or ridges in the granite bedrock. They are the result of liquid magma being squeezed along planes of weakness in the bedrock. The magma cools very quickly to form a rock which can be either softer or harder than the contiguous bedrock.

A four kilometre trudge down The Pyramids Road to the Castle Rock Campground knocked some of the gloss off our morning’s relaxed perambulations, but with a decent shower, a feed and one of Joe’s beers to slake our thirst, who could complain. Late in the afternoon, we saddled up again and headed off for the three kilometre round trip to climb The Pyramid (1080 m). Finally, for those of you who are familiar with this walk, I can report that the famous Balancing Rock is still firmly glued in situ despite Samantha’s determined efforts to unseat it.
