Info on the statues found here: Artwork of the Hoover Dam

Oskar J.W. Hansen designed the plaque commemorating the 96 men who officially died during the construction of Hoover Dam, as well as the bas-relief series on both the Nevada and Arizona elevator towers. The plaque, originally set into the canyon wall on the Arizona side of the dam, is now located near the winged figures. It reads:

"They died to make the desert bloom. The United States of America will continue to remember that many who toiled here found their final rest while engaged in the building of this dam. The United States of America will continue to remember the services of all who labored to clothe with substance the plans of those who first visioned the building of this dam."
