At the museum

there were many interactive exhibits. This one showed how much food a farm wife would have had to prepare for a threshing crew for one meal. We rode the flour tower which was an old freight elevator that showed us what might have been going on on the various floors of the mill. When we got to the ninth story we were able to go out onto a balcony and look out over the cities. We could see Saint Anthony's Falls and the Stone Arch Bridge. Saint Anthony's Falls are the only major waterfall on the upper Mississippi. The falls were replaced by a concrete overflow spillway also called an apron when they partially collapsed in 1869. In the 1950's and 1960's a series of locks and dams was created to further upstream navigation. The Stone Arch Bridge is the second oldest bridge over the Mississippi River and is now a walking and biking path.
