Title: Saint Anthony Falls
Passage: Saint Anthony Falls or the Falls of Saint Anthony, located northeast of downtown Minneapolis, Minnesota, was the only natural major waterfall on the Upper Mississippi River. The natural falls were replaced by a concrete overflow spillway (also called an ``apron'') after it partially collapsed in 1869. Later, in the 1950s and 1960s, a series of locks and dams was constructed to extend navigation to points upstream.
