Closer inspection of the structure, named the Blinkerwall, revealed about 1,400 smaller stones that appear to have been positioned to connect nearly 300 larger boulders, many of which were too heavy for groups of humans to have moved.

I’m sure they’re right about the larger boulders, but at the same time, it seems like a running theme of ancient civilizations to be able to move massive rocks around in ways that leave us simultaneously baffled and impressed. It’s like our ancestors were secretly in a competition to see who could do the most with giant rocks and stones.
