Hoover Dam - Construction

UNLV Special Collections

Workers are shown pouring concrete at Hoover Dam. Refrigerated water from the Colorado River cools the tubes within the concrete to help remove heat generated by the solidifying process. Only one worker has officially been buried at the dam. He falls into the river and is dragged to the bottom. His body is later found stuck inside one of the temporary structures called cofferdams.
