Important early map of Wisconsin Territory, extending to include all of present day Minnesota, the Upper Peninsula of Michigan and most of the Dakotas.
The western extent is the Missouri River up to the White Earth River. Outline coloring shows eight districts and numerous land parcels allocated to the various Indian tribes and areas ceded by the Sioux, Sac, and Fox. Filled with detail of forts, ferries, towns and villages including Wisconsin City and Milwaukee. Hydrology is well developed and there is considerable geographic data, preceding Nicolett's map of the Upper Mississippi Region.
Wisconsin Territory was created by an act of the United States Congress on April 20, 1836. The new territory initially included all of the present day states of Wisconsin, Minnesota, and Iowa, as well as parts of North and South Dakota. The present map accompanied the report of Z. Casey and is likely the first printed map of Wisconsin Territory.
