ca. 1935 — Original caption: President Roosevelt, high up on one side of the huge Boulder Dam at Boulder City, Nevada, points to one feature of the mighty structure, and asks a question. Walker Young, the engineer in charge of the project conducted the Chief Executive on a tour of the dam, after which Roosevelt made a dedication address, during which he pointed out that federal spending had given the nation useful works such as this one, and had started the wheels of private industry turning. — Image by © Bettmann/CORBIS
