Opalton – Lark’s Quarry – Old Cork Station

Wednesday 12 August

Left Opalton without finding our fortune in Opals. I am told that we did find some but I think a magnify glass is needed to see it. Went south then north west to connect to the Jundah Winton Rd and thence to Lark’s Quarry. This is the only known site of a dinosaur stampede in the world. 3300 fossilized dinosaur tracks are preserved in a specially designed building. Hundreds of small coelurosaurs and ornithipods stampeded to escape a large hungry theropod (or so the brochure states). The tracks of the therepod are certainly impressive.


He wouldn’t have been a welcome site whilst taking a walk in the bush!

Spinifex and termite country. One will burn your car, the other will wreck the suspension. When travelling over spinifex it is advisable to stop and check under the car every so often. We carry a long hook for pulling out the spinifex from under the car. It is very flammable and can be set alight very easy. It is also very prickly to walk through of handle.


Leaving Lark’s Quarry we headed for a camping site on the banks of the Diamantina River at Old Cork Station. Very corrugated road with lots of bulldust.






Old Cork Station is in ruins as the homestead was moved some time ago however the campsite was pleasant.



It is not possible to swim in most of the Diamantina as the banks are very muddy. Just camping beside water is great though, it certainly seems to lower the temperature. Packed up early the next morning and headed for the Diamantina Lakes National Park. P8110051



Very dusty road with few cars in fact I don’t remember passing another car all day. Passed through some huge cattle properties including Brighton Downs, Verdun Valley and Cork. Huge areas of Mitchell grass plains interspersed with rocky jump ups.


We have now entered sand hill country. Still fairly low and spaced a fair distance apart. The size will increase as we go west however as we are going to Alice Springs we will be on the northern fringes of the Simpson Desert. The sand hills run in a SSW – NNE direction with the eastern side being much steeper than the west. Hence most crossings of the Simpson are from west to east.
