In his classic study of the Great Plains, Walter Prescott Webb described the 98th meridian as the dividing line between the arid western United States and the humid eastern United States:^[1][2]

As one contrasts the civilization of the Great Plains with that of the eastern timberland, one sees what may be called an institutional fault (comparable to a geological fault) running from middle Texas to Illinois or Dakota, roughly following the ninety-eighth meridian. At this fault the ways of life and of living changed. Practically every institution that was carried across it was either broken and remade or else greatly altered.

More commonly, the 100th meridian is cited as the approximate dividing line, following the earlier observations of John Wesley Powell in the late 1800s.^[1]
