... Three radiocarbon dates on wood, including one on a log from the type section of the Two Rivers till, show that the age of this till unit is unquestionably Greatlakean (post-Twocreekan). The Two Rivers till, now formally designated the “Two Rivers Member of the Kewaunee Formation,” was named...

...-creekan wood at one locality, is correlative with the Valders Till of the Lake Michigan lowland, as is the age-equivalent Kirby Lake till. One Greatlakean till, correlative with the Two Rivers Till of the Lake Michigan lowland, overlies forest beds at several localities. Geological Society of America...

.... The Ozaukee and Haven tills underlie the Two Creeks Forest Bed. The younger Valders Till, although not present at a forest bed locality, is also pre-Twocreekan age based on several arguments including correlation with tills of the adjoining Green Bay Lobe. One Greatlakean age till, the Two Rivers Till, has...

... deposited during the Two Creeks interstade approximately 11 850 BP. Furthermore, the till overlying the bryophyte bed does not represent continuous deposition by ice throughout the Two Creeks interstade, as proposed by others, but represents deposition during the Greatlakean stade. A major implication...

..., during the post-Iroquois lake phases, glaciolacustrine clays were subject to distortion by ice action at the time of the Greatlakean stadial. This deformation was more severe at the east end of the basin. At its lowest level, the surface of early Lake Ontario following the post-Iroquois phases was below...

... final deglaciation produced many different lake phases, for example, in the Lake Huron basin from 14 000 to 10 000 uncalibrated radiocarbon years before 1950 (Fig. 2 ). Ice-lobe advances during the Port Bruce, Port Huron and Greatlakean stades contributed to lake-level highstands, whereas ice-lobe...
