1947 Map of Chesterfield

South of the river, the terrain rises into the rolling uplands of Meramec and Bonhomme, where established rural communities like Gumbo and Bellefontaine are connected by the Olive Street Road and Boones Lick Road. Local life centers around a network of country institutions, including the Chesterfield Sch, Trinity Ch, and Beeffee Ch. This era shows the region just before mid-century suburbanization, with the Chicago Rock Island and Pacific Road still a primary transport artery through the valley.
