The Bignell loess was named and first described by Schultz and Stout (1945). At the type section of the Bignell formation, near Bignell, Lincoln County, Nebraska, the upper loess (Bignell) is separated from the Peorian loess by a prominent soil and overlain by a complex topsoil. Condra, Reed, and Gordon (1947) have also described the Bignell loess. Various profile sections in this paper (figures 3, 7, 12 and 14) show that the Bignell loess is restricted to flood plains, terraces, and upland shoulders of the valleys of the eastern half of Nebraska. The Bignell loess has not been previously recognized in Iowa. The lack of a soil break in the buff loess of western and southwestern Iowa has been somewhat perplexing when one realizes that on the western side of the Missouri River valley in the vicinity of Blair, Nebraska, the soil separating the Bignell and Peorian loesses is well developed.
