The five sculptures were a Depression-era project cooked up by the Rapid City Chamber of Commerce, who saw them as a way to make jobs, get the government to pay for it, and capitalize on the flood of visitors to nearby Mount Rushmore. Emmit A. Sullivan is credited as the sculptor -- the same artistic genius who created the Christ of the Ozarks and the dinosaurs at Dinosaur World in Arkansas.
The dinos were dedicated on May 22, 1936, on the crest of a hill overlooking the city. The five figures -- an Apatosaurus, Triceratops, Stegasaurus, Tyrannosaurus Rex., and a Brontosaurus, were fashioned from concrete over iron pipe frameworks.
The Brontosaurus is 80-ft. long and 28-ft. high, standing at the highest point of the ridge. The other dinos are situated along walkways straddling the ridge and down the slope to the parking lot.
