Wow :
up close & all made from a continual, single pouring of concrete.
That just boggles the mind, "At 1084 feet tall". How did they manage to pump concrete that high? Just amazing, simply utterly amazing.

High pressure pumps from the hollow inside i guess.
Its pretty amazing what we can build. Still amazing they can pump concrete that high. I mean straight up pretty much, and wet concrete is not that light.
