Lake Border Moraine

rdf:langString Lake Border Moraine

rdf:langString The Lake Border Moraine (also called the Lake Border Morainic System) is a complex group of moraines bordering the southern end of Lake Michigan. It can be traced north along the eastern shore of the lake basin and across the highlands between the northern Lake Michigan and Saginaw Bay. It continues around the Saginaw Basin into the "thumb" of Michigan, and south through southeastern Michigan on the eastern side of the "thumb." Along Lake Michigan, north to Holland the system is close to the shore. From Holland north to Oceana County it is 15 miles (24 km) to 25 miles (40 km) east of the shore. In Oceana County it forms the prominent "clay banks" along the shoreline of Lake Michigan. It again bears inland from Hart, where more recent moraines reside between it and Lake Michigan. It runs north of the great interlobate moraine that exists between the Lake Michigan and Saginaw lobes of the Laurentian ice sheet. A little north of Cadillac turns to the east. A short distance from Cadillac, it splits with the southern ridge or outer member heading to the Saginaw basin. The northern ridge heads towards Lake Huron, but turns south before reaching the shore. In Newaygo and Lake counties it rest on an earlier interlobate moraine. It separates in Wexford and Missaukee counties to continue south along the west side of the Saginaw basin.
