Uluru (Ayers Rock) is a natural occurence, much the same as any another hill or mountain, I suppose. It's all got to do with erosion and the like, I expect.

Natural occurrence is for certain, weathering, erosion, and chemical spray, wind, ice wedges, man e.t.c. But what really gave it the only piece of rock standing. Does ice come involved, pressure release e.t.c. Does any one really know as I am guessing here?

I'll give you a quick snapshot and look up something decent but basically it was formed back in Gwondanaland times I think.

It's a sedimentary rock and when the earth was settling it developed sort of on its side. So what you see is only a part of it, sideways. Watch this space more to come.

I am familiar with 'Gwondanaland times', but don’t understand fully of sir exit 10 explanation on the occurrence of this monoliths.

Sorry about the delay folks and I'm a bit bleary-eyed at the moment but I lifted this info from


www.pacificislandtravel.com/australia/northern_territory/uluru.html

because I am a bit tired, and I need a spell checker, missed Gondwanaland the first time around.

There is some scientific disagreement about the origins of Uluru. The most widely held theory is that both Uluru and Kata Tjuta are remnants of a vast sedimentary bed which was laid down some 600 million years ago. The bed was spectacularly tilted so that Uluru now protrudes at an angle of up to 85°. The rock is actually grey but is covered with a distinctive red iron oxide coating.

Also there is a link to my town, don't know how accurate it is, didn't get a chance to read it.

Bedtime reading for you all.

In regard to Ayers Rock/Uluru. It's a geographic formation called an inselberg, where the softer materials around it erode and the harder material stays put. Back to the original question, (and this is just a guess)but it's likely that the Joseph Bonaparte thingys were named by La Perouse, who missed out on claiming Australia for France by a couple of days.

Mmmm, Ayers Rock/Uluru - my Uncle just re-climbed The Rock (third time lucky) and the traditional owners still don't like people to do this (apparently), but, geographically speaking it is referred to as a monadnock and is the world's largest monolith - a monadnock is a lone hill or isolated mountain of bedrock, rising above the surrounding area and is geologically thought to be a remnant from a mountain chain!
As for Picnic at Hanging Rock - total fiction, set in Victoria in 1900. Walkabout (1971) with British Actress Jenny Agutter and Australian Actor David Gulpilil (who was 15 years old at the time) portrays him at his brilliant best, and another 'out there' performance of his is in the film 'The Last Wave' . . . definately an acquired taste though . . . and David still awaits any royalties, he lives in a 'shed' (for want of a better word) with no running water etc, even though he is now nearing 50!

Engadine, while I don't know what a monadnock is look at this: www.abc.net.au/schoolstv/natural.htm I suppose it's possible that it's both things at the same time.

You're absotively right!
From an online geologic dictionary you get this meaning for the term monadnock . . . a mountain or rocky mass that has resisted erosion and stands isolated in an essentially level area. Also called inselberg!

Engadine, not an unusual situation e.g. abottle in front of me can be both a blessing and/or a curse. Fortunately for me, it's the former (I think).

Depends on what's in the bottle, or how much is left in the bottle, me thinks . . . . . . and I'll drink to that (lol) . . .
