The Way Out West exhibit, which is expected to open in late 2020, will take up much of two floors of the museum, which has been undergoing a major expansion that will help to accommodate this new permanent exhibit. It will start with the prehistory of the region and the now-extinct animals such as mammoths, camels and giant bison that used to live here and continue into telling the stories of the East Snake Plain Aquifer and other unique aspects of the region's environment and geology, the Shoshone-Bannock people, the Europeans who settled this area, the founding of Idaho Falls and the industries that sustained the region and much more.
