How big is Grand Coulee Dam?

Grand Coulee Dam dwarfs the Great Pyramids of Egypt and generates more power than a million locomotives. An engineering wonder, it is also the country’s largest hydroelectric project.
Grand Coulee Dam is one of the largest concrete structures in the world, containing almost 12 million cubic yards of concrete. It towers 550 feet above bedrock (as high as the Washington Monument) and is 500 feet wide at the base. There is enough concrete in the dam to build two standard six-foot wide sidewalks around the world at the equator.
