Photograph of Howard Hughes standing next to a table with an unidentified man. The two are looking over a sheet of paper Hughes is holding. They are possibly on a film set.
An image of Parker Dam on the Colorado River at the California-Arizona border, 155 miles downstream from Hoover Dam. Parker Dam is commonly referred to as "the deepest dam in the world" because 73% of the dam's structural height is positioned below the original river bed. Note: Boulder Dam was officially renamed Hoover Dam in 1947.
