defence?
No, de wall.
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... :D
Quotemany of which were too heavy for groups of humans to have moved.
At least no speculating on aliens! 8)
