***Glacial Geology of Chicago
***Quaternary Geology of Illinois
"The landscape of Illinois is the product of its most recent past, the Quaternary Period, roughly the last 2 to 2.5 million years. This period of geologic time, in which we live today, has been characterized by alternating glacial and interglacial episodes reflecting Earth's climate flip-flops between cooler and warmer intervals. During the Quaternary Period, over 90% of Illinois was glaciated, and the remaining 10% of the state was affected by glacier meltwater, dust storms, and a climate more frigid than that of today."
15,000 - 20,000 years ago was the last time a glacier moved through Illinois.
See: Why we study glacial and quaternary geology.
Review: What is a moraine? Unconsolidated material which glaciers pick up (debris) --it's a mile thick---. During warming trend, glacier starts to melt and no longer has the power and strength to move the material. Moraines are these deposits of glacial material that has been dumped.
