Indiana has experienced several glaciations in the past 2.6 million years. Immense sheets of ice, called glaciers, formed when snow accumulated over time, compressed into ice, and began to move under the pressure of their own weight. They flowed southward from Canada and dynamically changed the landscape through depositional and erosional processes. This story map focuses on the several different glaciation periods that sculpted Indiana's landscape.
