Show & Tell: How the Ice Age Shaped Indiana Landscapes @ TCHA History Center
May 24 @ 11:30 am – 12:30 pm
During the past ~2 million years the earth’s higher and mid-latitudes have experienced several periods of widespread glaciation, including continental-scale ice sheets.
Nearly all the current surface landscapes of northern and central Indiana reflect the direct and indirect impacts of glaciation. Ice sheets completely changed the surface drainage, blocking river valleys to create lakes, diverting river channels, and in some cases completely filling valleys with sediment. In this session we will explore the glacial geologic history of the plains, terraces, wetland basins, and soils that helped shape the ecological and human histories of our region.
