The Corps presented a miniature scale model representing several of the infrastructural innovations used to construct the South Jetty at the 1893 “World’s Columbian Exposition” (a.k.a. the Chicago World’s Fair) in Chicago. The South Jetty construction model was exhibited in the U.S. Government Building with other examples of river and harbor improvements. The model depicted the trestle system, a steam operated pile driver, and a model train with dump cars unloading miniature boulders. Photo published in The Book of the Fair, 1893.
