Step back 2.5 million years into a world that was anything but sweltering with “Discover the Ice Age,” a traveling exhibition enhanced with animatronic models and life-sized skeletons. Visitors can channel their inner cave people alongside a woolly mammoth, a saber-toothed cat, and a gigantic “terror bird” while exploring extinction and whether our planet might see another ice age. In the words of Witte curator Thomas Adams, “It’s a great opportunity for people of all ages to explore and learn about megafauna that roamed here in our backyard.”
