Northern Highway to The McLarty Hills

Crossing the Great Sandy Desert, the Grand Plan

In July and August 2014, a group of 3 Okas and 6 people set out from the Great Northern Highway

near Fitzroy Crossing in northern WA to cross the north western section of the Great Sandy Desert .

With us (Janet and David, Oka 148) were Dave and Pauline (Oka 137) and Deano and Kaye (Oka 413).

We each carried the maximum amount of fuel and water practical (around 300l of fuel and 250l of

water per vehicle), food for several weeks, 6 spare wheels (all the same size rims for compatibility) plus

a couple of spare tyre casings.

Between us we also carried 3 HF radios, 2 Sat phones, 3 GPS navigation systems, an EPIRB and an

array of recovery gear. All 3 Okas were fitted with diff lockers front and rear to cope with the expected

soft sandy conditions.

Our major safety concern was to avoid a vehicle roll-over at all costs, which is why we were so careful in

reconnoitring routes over sand dunes. Between us we felt certain we had the spares, tools and expertise

to fix or circumvent any major mechanical failure (we didnt actually have any) but a roll-over would

have have been a serious and possibly irrecoverable disaster.

Dave was the architect of the trip since he worked in the area for many years and had prior experience

of the terrain and awareness of the sites to be visited. The planned route was to follow former or

existing mining tracks or cut lines whenever possible (they may have been unused for up to 30 years),

our primary objectives being:

to reach the Dragon Tree Soak, a small permanent lake in a nature reserve in the centre of the

desert,

to locate the names of historical visitors to the area engraved on the rocks somewhere in the

McLarty Hills,

and of course, return again safely to earth.

Exploration of the Joanna Springs area would be a possible side trip if conditions allowed.

This is what Dragon Tree Soak shouldlook like, (courtesy of a photo from a previous travellerss

account from Exploroz), but we had no idea of the size or exact location in the McLarty Hills of the

engraved names:

Route Planning

Starting from the Great Northern Highway near Fitzroy Crossing, we planned to emerge from the

desert on the NW Coastal Highway near Sandfire Roadhouse, the full distance of the desert crossing

being around 800-900km which should take around 2 weeks. Alternative exit route strategies were

considered via the Edgar Ranges north west to the Roebuck Plains if the western route became

impassable.

A things transpires, due to emerging fuel concerns, we had to abandon the side trip to Joanna Springs,

which would have added around 250km to the route, and put that on the list for a future trip.

3/30

(about 400km) being the most challenging section. For most of that section there were almost no

visible tracks to follow, only feint Google Earth photos of tracks (which were a few years old) that I had

saved and geo-referenced for our mapping software before leaving home, and occasional exploration

cut lines from the 1970s and 80s, most of which are very overgrown at ground level.

We had some old mining maps of the 1980s and GPS track plots from a couple of previous expeditions,

but vegetation conditions can change significantly over just a few years, and even our most detailed

topographical maps (EOTopo 200K maps from Exploroz) showed no tracks at all for around 70km

where our route crossed the Calvert Expeditions route of 1896 (the feint yellow south-north line on the

map above). That 70km section would take us 2 1/2 days to cross.

27 July

We had all arranged to meet at mid-day at a point 70km south east of Fitzroy Crossing on 29 July to

start the crossing, but starting from 3 widely dispersed parts of the country, getting to the starting

point was our first challenge. We came up from Adelaide, Dave and Pauline came up from Perth, and

Deano and Kaye came across from touring in Queensland.

Coming up from Adelaide in less than a week, we completed the 1100km Tanami Track to Halls creek

and met up with Deano and Kaye in the caravan park at Halls Creek. We compared notes on our Okas

at some length and I did some maintenance work on the handbrake since the cable had slipped off its

pulley and was jamming and got badly frayed.

I tidied up the sharp hard frayed ends, wrapped them in tape, and to ensure the same thing didnt

happen again, I fitted a bespoke stop to the handle so that only fresh unfrayed cable went around the


4/30

pulley and freed up some cable at the handbrake end to compensate.

Apart from that we relaxed over a few drinks in the warm shade to discuss our future adventures.

At 5pm we called Dave and Pauline at Jubilee Station where they were visiting friends, and confirmed

when and where to meet them; midday on Tuesday at the Cherrabun turn off, 200 km west of Halls

creek, before heading south west into the Great Sandy Desert.

Tomorrow well refill all the water and fuel tanks and do some final shopping for supplies in Halls

Creek and set off west to a campsite on the Laura River.

This will be the final upload of our blog for a couple of weeks, there are no Telstra phone towers

between here and 80 Mile Beach on the other side of the desert.

28 July

Refuelled, regassed and refooded in Halls Creek we set off 70km west to a Laura River campsite which

Dave had recommended rather than the caravan congested Mary River rest area. A bit rough alongside

the old river crossing but we did some gardening and made the most of it.


5/30

29 July

We met up with Dave and Pauline at the Cherrabun T/O, after a 140km drive from our previous Laura

River campsite with Deano and Kaye, who we teamed up with in Halls Creek. They arrived one minute

early and we arrived one minute late, not bad after 2500km from Adelaide.

The first meeting of our 3 Okas:


6/30

[Note for the future regarding fuel: In hindsight, we should have gone the next 70km to refuel again

in Fitzroy Crossing. The 200km from Halls Creek had used valuable fuel which we were to need

during the latter stages of the desert crossing, but we didnt realise at the time quite how tough the

crossing would be on fuel.

We had worked on a worst case average fuel consumption of around 4km/l, as we had experienced

on the CSR, but actually it was twice as heavy for much of the crossing, averaging 2.5km/l for the

most challenging sections. A lesson for the future.]

We drove quickly though picturesque Cherrabun station on rough station tracks, keen to get camped

on an old abandoned WMC airstrip on the desert crossing proper.

8/30

We located the old WMC airstrip about 100km in from the highway and set up for our first camp.

We all had superb BBQ-ed Baramundi for dinner, courtesy of Dave and Pauline who had brought them

from Jubillee Station where theyd been staying (and obviously fishing).

A high flyer passed over our airstrip campsite, which seemed appropriate.


9/30

30 July

We passed the junction of the old 1980s WMC mining track with its still legible (and sadly accurate)

sign:

At the track junction we stopped for a group photo, in this area the track is still in very good condition:


10/30

We drove though an abandoned Aboriginal out station and refilled with water at their still working

water system, since we werent sure where our next water source would be.

A few km further on we met the junction of the McLarty Track and turned west.


11/30

The track deteriorated in visibility and quality as we headed further west but the purple flowers and

Holly Grevillea looks very pretty, when they werent blocking our way.

13/30

We camped 90km further on from last night, just off the track at an old mining campsite used by Dave

a few years ago.

We located their still working bore and drew water using Daves very effective flap pump. We didnt

know it then but this would be the last useable water we located until Sandfire Roadhouse a week and ahalf later.


14/30

To demonstrate the amount of recent vegetation growth in the GSD, this is a merged photo of the same

area now, and in 2010:

31 July

From here the track started to deteriorate further and became overgrown requiring frequent deviations

around thickets of small trees and bushes where we couldnt push through them. We only achieved

47km today.

One of the more obvious cut lines across a sand dune:

The camping arrangements were becoming more organised each night.

This was a tablecloth night:

1 Aug

Another slow day along the McLarty Track, we only achieved 44km today.

There is no dotted line on the map to follow for 70km across this section of desert, 2 1/2 days drive:

From Drop Box

We were on even more our own for this section, but we knew where we were and we knew what we

were heading for.

Fortunately there were still some signs of a track on the ground and occasional signs of human

presence to provide reassurance we were on the right line.

17/30

We passed the approximate location where the 1896 Calvert Expedition crossed our track. [Calvert

financed the expedition but it was led by Larry Wells, you can read the book of their explorations

online here]. They were heading north and having to cross thousands of sand dunes in the process,

whereas our track was predominantly east/west to minimise dune crossings but we still crossed more

than 100.

western Australia.


19/30

Two of Calvert/Wellss men (Charles Wells, cousin of Larry, and George Jones) died in the desert of

heat and thirst in November 1896, a days marchfrom Joanna Springs, but it took 6 months of

exhausting searches to find them. Their mummified bodies were eventually recovered and buried in

Adelaide.


20/30

Although we didnt reach Joanna Springs due to fuel concerns, there is a memorialplaque to the 2 lost

men, installed there by the Land Rover Calvert Centenary Expedition, (photo courtesy of Mick O on

Exploroz):

Back on our track the thickets were becoming thicker but at least we didnt have to find water for our

camels:

Occasionally they became thinnets:

Or grassy spinifex clumps:

And the same camping arrangements, on a clearing on the track:


23/30

2 Aug

This was the day we had to seriously start making our own tracks.

The dotted red line on the maps disappeared completely yesterday and today the tracks on the ground

did likewise. We were left with Google Earth photos and the track plot of a previous adventurer to

guide us. As a result we could only achieve 22km today.

Things started out OK


24/30

but became more difficult:


25/30

And collected some passing flora:


26/30

We did find a large spider hanging from silver threads of steel. He (or she) obviously knew how to

survive out here:

Heres a video of pushing our way across the desert spinifex. It started fairly easy but was to become

more difficult, much more difficult in the later stages of our trek.


27/30

3 Aug

After about 20km this morning we regained the red line on the map and reached the McLarty No 1 drill

site, but we couldnt locate their bore, so we had lunch here instead.


28/30

The McLarty No 1 drill site was made in 1968, with the details firmly etched into a piece of thick steel

plate.

We located the junction of the Edgar Ranges Track from the north which showed some evidence of

recent wheel tracks (a day or 2 old) although we never saw anyone, and turned south down the

McLarty Hills track which was an old mining cut line but now mostly very indistinct and overgrown.


29/30

A star picket is a valuable indication of human presence:

We managed a bit further today, 32km, but it was hard slog and we were getting tired so we made

camp a few km short of the McLarty Hills, they could wait until tomorrow.

Camels came to visit our campsite, but they were more curious than threatening but we were very

cautious, large male camels can be very protective of their harem if threatened:


30/30

As I explored the facilities around the campsite I noted that its so dry out here your wee dries up

before it hits the ground (almost, men only).

Tomorrow we should reach the McLarty Hills, our first major objective. See Exploring the McLarty

Hills.
