Originally a natural waterfall over Platteville limestone, but the soft St. Peter sandstone underneath eroded so quickly that by 1869 the falls were collapsing. The Army Corps of Engineers built a concrete spillway to stabilize it. The falls today is a managed feature, but the geology that created it is the same as Minnehaha 8 miles south.

Why is it called St. Anthony Falls?
Named in 1680 by Father Louis Hennepin, a Belgian Franciscan missionary, after his patron saint Anthony of Padua. The Dakota name was Owámniyomni, meaning turbulent water.
