Geosurvey Hill to the Colson Track

No, but have done from near Poeppel Cnr (Mirroponga Pongunna Lake) to the Geos, and it is VERY tough going.
Mid year 2015
We bailed out about 6km east of Geo Hill, due to very high fuel use with steep eastern dune faces, went WAY back past Geo centre again, and down to French Line to bail to Mt Dare, only just making it.

Many dunes took several goes, often lead vehicle would make it, but sand then disturbed so next would have to take another route / line.
Very slow, and between dunes slow with spinifex clumped ground.

We successfully went the other way in 2017, and after seeing the dunes behind us knew then we amde the right choice back in 2015, we would not have made it, even though distance wise it was a lot closer to continue to Colson, and out via Madigan / Old Andado / Binns Tk.

Currently organising another one through there this year . . . a double NT Simpson crossing.
Madigan East - West to Mt Dare.
Geo centre (at least, maybe Hill + 100km return) . . . via French Line, Colson, old shot line from just up Colson to lower Geos corridor, then from centre cross country to Beachcomber on Hay River Tk, back to BV.

Thanks Les, yes we are still working on whether we will attack east to west or vice versa, may not be worth the heartache or the fuel lol.

Hi aussieranger

I would go as far as to say it is totally impossible.

What I can tell you is out in the centre of the Simpson, there are many dunes that will make Big Red look like a little Red.

The virgin dunes are deeply covered in dense cane grass, mogals, that are often hard enough from the west and daunting from an east approach.

One thing that we learnt from the very first dune that we crossed was a retread would be impossible and the only way out would be a very slow rock and roll down the dune swales to the French Line. Our first night out in the remote Simpson was at the bottom as a rather small dune, and one chat in our small group with a very worked over V8 Cruiser, said it would be an easy job to tackle, so he locked in both front and rear lockers, and after 7 tries, could not get more than half way up, so he had to admit defeat.

Those that say it is possible will have never been out there, as this is no ordinary Simpson trip.


Cheers
