Here we reside at the Glaciers end.
In general, geologists divide these events and the glacial deposits of the Ice Age into three great stages, each of which experienced several ice advances:
- The Wisconsin Stage, which began about 50,000 years ago. Nearly all of the modern landscape of the northern two-thirds of the state, and a large part of the deposits beneath, are the product of this stage.
- The Illinoian Stage, which took place from about 300,000 to 140,000 years ago. These deposits are exposed at the modern land surface in southeast and southwest Indiana, beyond the limit of the Wisconsin ice sheets. They also occur in the subsurface throughout the rest of the state, beneath the overlying Wisconsin deposits.
- The pre-Illinoian Stage, which is much less clearly understood and includes everything else before the Illinoian. Several events from this stage are known to have affected Indiana, and the deposits that record them occur in widely scattered localities in the subsurface.
