The thick Cretaceous sections in western Montana, western Wyoming, and Utah are correlated in this stratigraphic section. Lithostratigraphic, chronostratigraphic, and sequence stratigraphic data are compiled from the four east-west sections to be displayed at this meeting. The sections parallel the basin margin and display thick nonmarine fluvial coastal and plain deposits with intertongues of marine strata.
