This is a very boring photo at first glance, just some rocks, but read on if you'd like to find out why it's not boring in the slightest, or toddle on & have a good day, thinking it is!
Last week I finally got to return to an area I hadn't been to since the mid 90's. The site of a conundrum of huge magnitude that has scholars, professors, historians, anthropologists & more still scratching their heads in confusion.
This photo was taken amongst a large clump of huge granite outcrops in the country. This granite boulder has been drilled into & split, using techniques & tools not known to have been present here at the resultant time that the carbon dating tests of the drilled sections of this granite suggest. The boulders are ages old, the drilled sections are many thousands of years old. There are no indicators in Australia of any types of settlement of communities being here those many thousand years ago, apart from the indigenous peoples of Australia & they didn't work with stone & metal implements in this way, ever! It is not something that can be achieved with timber implements alone, this requires the use of a drill-bit of sorts, that you would whack damn hard & spin around with your other hand constantly, so it worked like a drill-bit does in an electric drill, but very, very slowly. Then wedges are placed in the holes & progressively tapped in until the rock splits along the drilled sections. This technique is still popular with old school masons, but they use electric drills to bore the shafts.
The shafts here are almost perfectly straight on the sides of them, which when you see rock split using the manual tap & spin method, the sides are anything but straight! Further adding to the confusion of who did this & then there's the matter of why?
If you look along the top section of the split of the right side rocks you will see the line of the drilled holes & on the diagonal rock on the middle & bottom left you can clearly see some of the the drilled sections that would have had wedges drove into them progressively so as to split the rock.
So here is my boring photograph of some rock.
