The two elk at the top of the Vista are the work of French sculptor Prosper Lecourtier (1855–1924), a specialist in animal figures. Lined with Japanese cryptomeria, pink flowering horse chestnuts and pin oaks, the Long Walk extends from the Mansion to the Reflecting Pool.
The 157 jets at the center of the one-acre pool shoot water 12 feet into the air; when they are turned off, the entire "Long Walk" is reflected in the pool. The pool, five and a half feet deep in its deepest section, holds 800,000 gallons of water and takes three days to fill. The Art Nouveau-style, classical mythology-based “Four Seasons” around the pool are by French-born American sculptor Henri Crenier (1873–1948).
