Iron age hill forts and stone age burials can be very prominent features of the landscape. It's not just latent, occasional traces like the ones that have become visible in the last few weeks which survive. They could build to last in the stone age, and there's no reason to believe that they would be surprised that their monuments are still standing today... When it comes to the latent evidence of human occupation, I guess it's a bit more unexpected for it to become so visible to us. But even stone age cooking fires leave very permanent traces. https://en.wikipedia.org/wiki/Fulacht_fiadh https://en.wikipedia.org/wiki/Fulacht_fiadh
