This map of Duluth and the surrounding area as of 1865 was drawn by R.E. Carey based on old records and memoirs. The accompanying booklet, also by Carey, describes historical sites in Duluth, which are number coded on the map. Sites include early houses, a sawmill, a schoolhouse, an early brewery, the Vermilion Trail, and a stone quarry.
This 1921 street map of the Duluth, Minnesota, and Superior, Wisconsin, area includes streetcar lines, railroads, parks, schools, farms, cemeteries, docks, grain elevators, the Duluth-Superior Ferry Line, the Duluth Boat Club, and other details. There is a separate index for both Duluth and Superior.
