The image shows large cylindrical structures which are characteristic of grain elevators used for storing and transporting grain. The presence of a ship docked nearby suggests it is located along a river (in the Chicago area as per the option). Canal loading zones and slaughterhouse docks have different typical structures. A cement factory would have different equipment and storage units compared to the cylindrical silos seen here which are typical for grain.
