View of the Hoover Dam construction site in Black Canyon, showing the nearly-completed dam face and construction on the power houses in the lower cofferdam. Concrete pouring forms are seen on the tops of the power houses. Temporary buildings, construction equipment and trucks are seen on the cofferdam floor. Cableways run over the canyon above the dam face and a section of penstock tunnel pipe is seen being lowered into the cofferdam. Construction on the Arizona valve house is seen on the right side in the center of the canyon wall. One of the diversion tunnel portals is seen in the lower left.
