Ok, I have got some more pics to post, so here goes in order of appearance.
An unusual looking cloud over the Flinders Ranges north of Hawker
At Marree - Tom Kruse Birdsville mail truck (saw another one in Port Augusta too) with Marree Hotel in background.
Old wells at Coward Springs, on the Oodnadatta Track which was one of the stations on the old Ghan railway.
On the way out to Lake Torrens from the opal mining town of Andamooka which is 30km east of Roxby Downs.
The remains of the Redstone rocket which were retrieved from where they fell in the desert, on display at Woomera.
Once I had done that loop I headed north from Port Augusta into the Flinders Ranges again.
This is the view from Sillers Lookout, which is the final point on the Ridge Top Tour at Arkaroola Wilderness Sanctuary, looking east to Lake Frome (~50km away) which you can just see over the hills. You might have seen this tour on TV, I think it was on Getaway or something - it is fantastic. You travel out into the hills on a mining exploration track. One way of gauging how rough and steep it is, is the fact that the tyres on the Landcruisers wear out in 6000km! The views and scenery are incredible.
This is the hill I went up, the track to the right goes around the bottom of the hill. Not a fantastic photo as it was taken through the windscreen.
This is the view back down the hill, note that the camera has a wide-angle-ish lens so the hill and the bumps appear a lot flatter than they actually are.
This is part of the southern Flinders Ranges near Wilmington.
There are a lot more photos but a lot of them are of the featureless plains from Roxby Downs down to Port Augusta (got to do something to occupy yourself on that road), and also more of the rugged hills in the northern Flinders Ranges. Unfortunately by the time I got to Wilpena Pound the memory card was full, but at least I did get some shots on film from St Mary's Peak.
