Bushwalk Australia

Found this carving atop the tallest rock on a high ridge...Any ideas on what the sigificance is? Its a deep circle with directional like arrows shooting off at different angles.

A quick guess I'd say a survey mark. The hole could be for locating a plumb bob on a theodolite and the radial lines point to something of interest to the surveyor. But then again I'm not a surveyor so I could be really wrong.

Where was this?

Points of the compass.

What the hell did you take this photo with? A pinhole camera?

thats an insult to the makers of all pinhole cameras,....

Well i don't know what a pinhole camera is,,,so I'm going to say no.

The reason the photo is so poo... is bcause it kept telling me the picture was too big, SOO I mucked around with resizing it and that's how it turned out?

I don't know stuff all about puters really so that was a strectch in itself!

Where was that Like button again?

This one any better?

Nah...Still sucks. Back to the drawing board for me.

was it a prototype digital camera? 0.1megabyte?

Open the original photo in paint and Resize by whatever percentage gets it down to a sensible size.

I'd guess some kind of trig point.. did the place in question have a spot height on the map?

Look at the weathering and natural erosion of the carving. Combined with the exposure of the location will give you an idea if its tens or hundreds of years old.

Where was this located - that might give us some clues.

Because its probably from a stereoscopic or advanced 3D camera, I offset it and ran it through a polarising filter to offset the earths atmospheric affects.

Holy *&%$#!. It's a message from the aliens signalling the end of the world

An intercept !

Old trig point; although the major ones normally have a bronze datum marker

FastStone Photo Resizer 3.1 - its freeware, its fast. Can convert/resize/watermark a whole batch of files in seconds.

It was well and truely weathered, hidden under a thick coverage of moss, leaves, stick and branches. I was up there having a rest and one of the lines, the longest one which points South, caught my eye so i cleaned it out.

I thought trig point too but there is no sign of modern construction like bolt holes or a cement plymth etc AND there is 2 actual exsisiting trig points, say, a Klm each side of it.

Interestingly it is just above some excellent camp caves and located not far is some other secret Aboriginal art I've found.
When my ingrate daughter finds time out from her busy schedual of facebook and surfing I'll get her to put up some better pics.

Its a survey mark, they may never have actually placed a trig over the top of it, it could just be a surveyors reference mark rather than a trig point
