Mitchell comity is located in central northern Iowa, bordering the state of Minnesota on the north, Howard county, Iowa on the east, Floyd county on the south, and Cerro Gordo and Worth counties on the west. It is entirely within the Iowan drift soil area and most of the soils are of glacial origin.
