![]() Glacial GeologyGlacial geology is important in Illinois' most recent geologic past, the Quaternary Period (also called the Ice Age), during which continental glaciers repeatedly plowed across the state eroding and redistributing material and creating new landforms. Today, Illinois is experiencing an interglacial episode, a relatively quiescent and warm interval of the Quaternary Period that allows the soil to form and crops to grow. Quaternary geology encompasses both the cold and warm intervals and the glacial and nonglacial processes of the past 2 million years. Why
we study glacial and Quaternary geology Maps
