Hoover Dam (formerly Boulder Dam), under construction in 1934. The black-and-white image depicts an enormous pipe being moved from one side of the canyon to the other. A man, barely visible in the image, kneels inside the pipe. The dam itself is visible at the bottom of the frame, surrounded by the walls of Black Canyon.
