This Museum located in the basement of the Tabernacle houses the Upper Snake River Valley Historical Society Museum aptly named the Teton Flood Museum because of its extensive collections of flood memorabilia including but not limited to films, photos, and other items related to the Teton Dam disaster. The upstairs of this building is used as a civic auditorium which seats 1000 people and is well known for its excellent acoustics.
There are many pioneer relics, depicting the lives of early pioneers, an Idaho opal/agate collection, North American animal head collection, World War I and II items and much more.
History was written in the landscape of the surrounding communities by the scouring floodwaters of the Teton Dam on that fateful day, June 5, 1976. Much of the damage has been rectified but there are still tell-tale signs of the overwhelming devastation caused by the flood that can never be erased. A high water line marks the entrance to the museum indicating the level of flood water from the 80 billion gallons of water that came through Rexburg.Exhibits have been made possible through many donations, memberships, and other support of the museum. Many one of a kind items are housed here.
