St. Louis According to the United States Census Bureau, St. Louis has a total area of 66 square miles (170 km2), of which 62 square miles (160 km2) is land and 4.1 square miles (11 km2) (6.2%) is water.[39] (Not shown on simple maps of the city, the land at its airport is owned by the city, served by its fire department and others, and is an exclave of St. Louis.) The city is built primarily on bluffs and terraces that rise 100–200 feet above the western banks of the Mississippi River, in the Midwestern United States just south of the Missouri-Mississippi confluence. Much of the area is a fertile and gently rolling prairie that features low hills and broad, shallow valleys. Both the Mississippi River and the Missouri River have cut large valleys with wide flood plains.
