This map of Wisconsin Territory shows county development as it stood in 1842 with the recent formation of Richland County in the southwest from the large Crawford County, which was organized in 1818. The border with Michigan is here shown along the Montreal River to Lake Superior. Carver's Claim and numerous Indian lands are located. Samuel Augustus Mitchell would take ownership of Tanner’s plates approximately two years later and publish it in the Universal Atlas.
