Survivors say the wall of water was like a tsunami that destroyed nearly everything in its path as it roared through a Black Hills canyon and into town. The flash flood that hit Rapid City, S.D., on June 9, 1972, was one of the worst floods in U.S. history. It killed 238 people and damaged or washed away more than 1,300 homes.
On Saturday, the city will read the names of those who died and reflect on how the flood changed the way the city and others towns across the country built themselves.
