In June of 2009, I visited the Geographic Center of the United States in Kansas. The final point, the northernmost point, was something I had planned later in that trip. The northernmost point is a geographic anomaly. It is the only point in the continental United States that lies north of the 49th Parallel. It is technically part of Minnesota, but it is not connected to the rest of Minnesota by land. This 116 square mile section of land is only part of the United States due to an incorrect understanding of where the source of the Mississippi River was and a mistake made by the first map makers in the area.
