Iowa
Geography
Iowa is bordered by the Mississippi River on the east and the Missouri River and the Big Sioux River on the west. The northern boundary is a line along 43 degrees, 30 minutes north latitude. The southern border is the Des Moines River and a not-quite-straight line along approximately 40 degrees 35 minutes north, as decided by the U.S. Supreme Court in Missouri v. Iowa (1849) after a standoff between Missouri and Iowa known as the Honey War.
