Artist Isidore Konti, born in Vienna Austria in 1862 and came to the United States in 1890. created sculptures that adorned the side Cascades. Small sculpture groups sat beside two large sculptures.
The large sculptures represented the Atlantic and Pacific Oceans. A powerful male figure with a soaring eagle at his feet represented the Atlantic Ocean. The Pacific was shown as a woman with an albatross at her feet. Konti's sculptures symbolized the importance of the Louisiana Purchase in connecting the U.S. from the Atlantic Ocean to Pacific Ocean.
