For the trivia buffs.....On top of the dam, two "Winged Figures of the Republic" dominate the Nevada approach, They are the work of sculptor Oskar J.W. Hansen, a Norwegian immigrant who was appointed a consulting sculptor by Secretary of the Interior Harold L. Ickes following a national competition.
Hansen said the 30-foot bronzed statues represented "that eternal vigilance which is the price of liberty." Perched on six-foot-tall cues of gleaming black diorite, Hansen's figures flank a 142-foot flagpole. In front of this array he placed a terrazzo star map depicting the celestial alignment from that site on the evening of September 30, 1935, the day President Franklin D. Roosevelt dedicated what was then called Boulder Dam.
