Museum of Rexburg: Teton Flood Exhibit
Rexburg, Idaho
Lots of official black and white photos and an occasional miniature model show what happened when the Teton Dam collapsed in 1976. An estimated 80 billion gallons of water scoured Rexburg, killing nine people. A line on the wall of the museum shows the high water mark of the "unforgettable calamity." There are a few mud-caked mementos on display, and a ten-minute film tries very hard to convey the magnitude and mess of the event.
In 2016, after receiving complaints that the Teton Flood Museum didn't have enough Teton Flood exhibits, the Rexburg city council simply changed the museum's name to the Museum of Rexburg. But the flood exhibits are still in it.
