Lithostratigraphy: Mackinaw Member
Chronostratigraphy: Cenozoic Erathem >>Quaternary System >>Pleistocene Series
Remarks
The lithogenic-based Batavia, Mackinaw, and Wasco members of the Henry Formation defined by Willman and Frye (1970) are not retained as formal lithostratigraphic units; instead, the names are retained for informal sedimentary facies that are helpful in understanding glacial history and predicting relationships among materials.
