Continuous Deposition ◽  
Glacial Lake Algonquin

New radiocarbon age dates for the Cheboygan bryophyte bed in northern lower Michigan indicate that the bed was not deposited during the Mackinaw interstade, as was previously proposed, but is correlative to the Two Creeks forest bed 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 resulting from the reassignment of the age of the Cheboygan bryophyte bed is that the Straits of Mackinac could have been ice free during the Two Creeks interstade and that during that time the Kirkfield phase of glacial Lake Algonquin may have extended into the Lake Michigan basin.

Straits Of Mackinac

Near the Straits of Mackinac, the Limenitis arthemis population on Michigan's Upper Peninsula consists mostly of the disruptively banded L. a. arthemis, while the population on its Lower Peninsula consists mostly of the unbanded, mimetic L. a. astyanax and arthemis–astyanax intergrades. Except at the straits, the Upper and Lower peninsulas are broadly separated by lakes Michigan and Huron. On the Lower Peninsula, arthemis-like forms are most common on the shore close to the Upper Peninsula but are much less frequent only 20 km south, probably because of the northward flow of astyanax genes. Neither population is in Hardy–Weinberg equilibrium because of a deficiency of "hétérozygotes," possibly because of cross-lake emigration at the straits.
