Postpiles like this occur when large pools of basalt cool under a glacier. The lava freezes on all 6 sides, and then slowly cools on the interior. But because it shrinks as it solidifies (unlike water), that puts the interior under tremendous internal stresses, which tend to break along hexagons (with occasional pentagons and septagons thrown in) because that’s a shape that tesselates while also minimizing perimeter to area ratio (ie the least amount of high-energy cracking needed per volume). And then at some point something weathers the top and sides so you can see it. And yes they are this cool in person.

This formation is close to a glacier. Not sure which one, but you can tell from the telltale blue-green water, which indicates a high concentration of the type of superfine sediment that you get in glacial runoff. And that is also amazing to see in person (water is actually fairly rarely really blue).

Thanks for the explanation! Giant’s Causeway in Northern Ireland/Southern Scotland is another example.
