The city of St. Louis is located on 61 square miles just south of the “Meeting the Rivers”, where the Missouri and Illinois Rivers join the Mississippi River.
The metropolitan area, which houses approximately 2,5 million people, is a relatively short distance by airplane, automobile or train from such other cities as Kansas City (250 miles), Chicago (300 miles) Indianapolis (250 miles) and Memphis (300 miles).
Much of the City of St. Louis is described as rolling upland, but I would say it’s really more flat than rolling, with a few gentle rises, and steeper slopes adjacent to the River des Peres valley in Southwest and Southeast City.
The highest points in the city include “Hi-Pointe” at Clayton Avenue and Skinker Blvd./McCausland Ave., and the Grand/Olive intersection. The low-lying Mississippi riverfront areas, both north and south of downtown, are protected by floodwalls and levees that withstood even the 1993 floods. The Riverview Drive strip north of Baden also lies in the floodplain. The downtown core is not flood-prone, but the levee and Leonor K. Sullivan Blvd. itself do periodically flood. The River des Peres floodplain includes portions of the Carondelet, Patch and Boulevard Heights neighborhoods, as well as parts of Willmore and River des Peres Parks. Although the City does not have many rocky bluffs over the Mississippi, locations like Chain of Rocks Park, Bellefontaine Cemetery, O’Fallon Park, the Archgrounds, and Bellerive Park are positioned high enough to provide panoramic vistas of the Mississippi and the American Bottoms in Illinois. Besides the River des Peres, very few open streams flow through the City; most have been converted into sewage tunnels as part of the citywide combined stormwater-sewage drainage system.
