I must admit I am slightly sceptical about it being an elongated hunting fold - just seems a tad long and unnecessarily hard work for that - but it is not as if I have a brilliant alternative to offer other than the hackneyed old "religious / tribal boundary marker" which tends to get trotted out when we do not breally have a clue...

many of which were too heavy for groups of humans to have moved.

At least no speculating on aliens!

A pity no map or diagram showing the shape. There is a suggestion that it has a shape so presumably not straight but ...?

There are maps in the original academic article at https://www.pnas.org/doi/full/10.1073/pnas.2312008121 but not the easiest to interpret.

Thanks Duncan - I see what you mean - eventually you do get a close up the map and scan labelled 2B and 2C - essentially a wavy line.

If it was in Egypt then it could be in de nile

With a bit more time to look further I actually find myself less convinced about human origin for this feature. The lack of stones to one side suggests nature may have had a hand here. Even the text does not seem totally convinced in places but still goes on with a large amount of entertaining speculation.
