north and east along a line in Michigan extending from Holland eastward through Kalamazoo to Jackson. Beginning 14,000 years ago, the glacial lobes had cleared the valley of the Kankakee River of ice. At this point, the forward movement of ice coming from the north equaled the rate of melting over the summer season. Now stagnant, glacier provided a continuing source of ground rock and soil to the southern edge of the glacier, creating the Valaparaiso Moraine and releasing vast quantities of water, sand and silt into the valley beyond. The water created Lake Kankakee, flooding are area from Momence, Illinois upstream to the east to South Bend, Indiana with a southern pool reaching from Watseka, Illinois east to Monticello and Winamac, Indiana. Lacustrine deposits are those deposited in lake water and only when the lake drains or the land rises, does it become dry land. Most of the soils throughout the counties surrounding the Kankakee are loamy (up to a quarter clay, quarter to half silt with less than half being sand.)[3] The outwash plain is underlain by sand with gravel inter-bedded throughout. The prevailing westerly winds began to treat the 'Lake Kankakee' like the shores of Lake Michigan. Dunes began to form along the south and eastern shoreline. Where ice blocks had been left behind, sand filled the depressions. Runoff from the Valparaiso Moraine built [2] outwash ridges of sand leading into the lake. On the south, the winds built dunes. As the volume of water decreased from the glacier melting northward, the lake slowly drained and filled. Not being able to cut a channel through the limestone ridge in Momence, the Kankakee Lake became 500,000 acres (202,346 ha) of marshland. Aeolian sand The Aeolian sands form the southern boundary of Lake Kankakee as they result from the wind moving sand from the shoreline inland. This feature begins in the northeast along the Maxinkuckee moraine of the Saginaw ice lobe in Marshall County, Indiana near Lake Maxinkuckee and Culver, Indiana. While a few dunes are found on the moraine, the sand beds are along the western edge. The Maxinkuckee moraine follows the north side of Tippecanoe River into Fulton County eastward towards Rochester. The southeastern edge of the sands, swings south and west through Cass County, to west of Logansport, turning west and passing north of Lake Cicott. Here a sand ridge forms the east border of the
