Lithostratigraphy for Quaternary glacial deposits: “If it ain’t broke, don’t fix it!”,

• (A response to an article by Räsänen) Räsänen and others (2009) claim that lithostratigraphic classification of Quaternary glacial deposits is so problematic that it is time to use allostratigraphy instead. Our immediate response from a Midwest perspective is—what problems? Formal lithostratigraphic classification of glacial deposits works. Since its initial use to define Pleistocene units in the Midwest (Willman and Frye, 1970), there has never been a serious reason to question this practice. Indeed, formal lithostratigraphies have been progressively established in most Midwestern states.
