First, it not that difficult to think of piling rocks, that's why it's common.

Then, northern civilisations: of course there is nothing in Antarctica and the Arctic... there are no human civilisations in the Antarctic and humans living in the Arctic usually do not build permanent structure.

As for northern civilizations... it's tricky. Building a monument like this supposes a complex society (a powerful and rich government) that is able to build large structures: so you find some in China for example (it's not that complicated to pile rock). Not really in Europe and North American because before the Middle Ages they didn't have the wealth, when they did (by late Antiquity), it just wasn't the style anymore).

What you find a lot in those places is earth pyramids, tumulus. So yeah they kinda build those.
