Central Duluth at the end of the 1920s represented two generations of growth and building at the northwestern terminus of the Great Lakes waterway. The 1870 nucleus of settlement was located in the upper center of the picture, at the base of Minnesota Point. Hardware and grocery warehouses and freight sheds lined the slips which opened to St. Louis Bay (right). Predominantly white-collar residential areas spread northeastward between the Lake Superior north shore and the escarpment (top).
