Today marks ninety years since construction began on the Hoover Dam. The highest concrete arch dam in the United States, it was designated a National Historic Landmark in 1985 and draws millions of visitors each year.⁠ A feat of engineering, 112 deaths were reported in association with its building. A memorial, inscribed "They Died to Make the Desert Bloom", was designed by Oskar J. W. Hansen, whose Art Deco sculptures dot the site.⁠ For more Hoover Dam history from gettyarchive, follow our bio link.⁠ 📷: Dick Whittington Studio/University of Southern California/Corbis via Getty Images l 1934 l #GettyImages25 #PreservingThePast #GettyArchive⁠ ⁠ #hooverdam #boulderdam #dickwhittingtonstudio #universityofsoutherncalifornia #blackcanyon #coloradoriver #greatdepression #americanlandmark #USlandmark #architecturephotography #engineeringphotography #FDR #landscapephotography #onthisdayinhistory #onthisday #lakemead #bouldercity #engineeringhistory #UShistory #historyphoto #historyphotographe...
