Abstract

Almost all of the main channel of the Kankakee River in Indiana is channelized. In Illinois, most of the river remains a naturally meandering stream. The geologic framework of the river as we know it today was established at the time of the melting of the last continental glaciers, from 16 000 to 13 000 yrs ago. Since then the river has carried great quantities of sand westward. Most of the landscape adjacent to the river in Indiana is sand, it includes silty and clayey glacial tills, silty and clayey lacustrine sediment, exposed bedrock and sand. In the area between the cities of Momence and Aroma Park the channel contains a series of massive sand bars, up to 1 or 2m thick, overlying bedrock. The upper (E) end of Six Mile Pool contains thick sand deposits. In the lower W end of the Pool the main channel is underlain by bedrock although the insides of the meanders have sand bars.-from Authors
