Idaho collections The museum owns permanent collections pertaining mostly to Idaho history across several disciplines, including archaeology, paleontology, and geology, as well as native inhabitants and early settlers. Museum staff curates in-house exhibits centered around these collections. The museum also houses the archaeologically significant Wasden Collection, which contains thousands of objects and fossils, including mammoth and other megafauna remains excavated from an archaeological site in the desert west of Idaho Falls. Other notable artifacts include a life-size
Columbian mammoth replica, a unique
Revolutionary War-era American flag, the Northwest's oldest English-language monument, and remnants from the nearby
National Reactor Testing Station's pioneering early research on atomic energy. The museum's flagship permanent exhibit, "Way Out West," is divided into seven galleries: • Idaho Origins (early Idaho history and fossils) • Out of the Rocks (geology) • Into Nature (flora and fauna) • People & Places (including sections on the
Shoshone-Bannock Tribes, trappers and traders, mining, homesteading, railroad, and agriculture) • Regional Roots (including “Eagle Rock, USA,” a walkthrough of a street in the 19th-century frontier town before it became
Idaho Falls) • A Complex State (items pertaining to Idaho's statehood and issues of discrimination) • Idaho Impact (Idaho technology and the state's public image) The Marie Putnam Discovery Room includes kids' play areas relating to early settlers and natural history.
Research and archives The museum houses an active collection and continues to collect artifacts, objects, documents, and photographs, as well as stories through an oral history project. The archives are open to the public and researchers by appointment. Archaeologists may submit proposals to perform research on the museum's Wasden Collection. ==Special exhibits==
