Discover what Iowa looked like when giant mammals roamed the landscape, glaciers shaped the land, and temperatures were far colder than today. Learn how the first people to call Iowa home adapted to these challenging conditions and explore the evidence they left behind. The program will also feature a display of real and replica artifacts from this fascinating period, offering a hands-on look into Iowa's earliest human history.
