Gutzon Borglum War I while flying for the Lafayette Escadrille. It is located on the grounds of the University of Virginia in Charlottesville, Virginia. Four public works by Borglum are in Newark, NJ: Seated Lincoln (1911), Indian and Puritan (1916), Wars of America (1926), and a bas-relief, "First Landing Party of the Founders of Newark" (1916).

Scott was completed in 1933 and stands at the peak of Mt. Tabor. Borglum
