Talk:The Bulwark

Even though it is described as having been built, The Bulwark strongly resembles a form of naturally occurring extrusive igneous rock called Columnar Basalt. A particularly famous occurence of which is at the Devil's Post Pile National Monument, eastern Sierra Nevada. Seriously cool stuff, I think they have a geology nerd at Bethesda somewhere.
