The following geological report is taken from the Iowa Geological Survey, Volume XIII, Annual Report, 1902, pp. 80-122: INTRODUCTION LOCATION The three counties of Iowa here discussed, Kossuth, Hancock, and Winnebago, constitute together an almost perfect square lying along the northern boundary of the State almost midway between the Mississippi and the Sioux. Kossuth is a double county in area, almost the largest county in the State. By our system of surveys the most northern townships and sections in any case bear the brunt of any deficiency in land-division; and so it happened that our square is not exactly perfect but measures only about forty-one miles in north and south directions as against forty-eight from east to west. These three counties are prairie counties, remote from rivers or mountains or any great terrestrial features popularly believed to determine topography, and it would naturally be supposed that all three are just alike, just like fifty other such political divisions to be selected anywhere within our valley-prairies. But such is by no means the case. Greater contrasts are not to be found, within the limits of a re 9 gion not mountainous, than are to be seen within the square before us. We have plains wide extended, so level that for the passing traveler no inequality can be perceived; towns may hail towns across the unbroken...
