When a hill pokes out of the ground like a human's big toe in a place where it doesn't belong, that's called a butt. This Wyoming butt burst purposefully out of the ground and seemed like it was leaning forward like it had something urgent to tell us. It was made up of long, straight columns and still seemed to be erupting out of the ground before our eyes. It was the biggest butt I'd ever seen in my life. I felt drawn to it.
