The Angle Inlet School is the last one room schoolhouse left in Minnesota. The school is located in the Northwest Angle, a fascinating geographical location. It is the only place in the United States besides Alaska that sits north of the 49th parallel, the geographic border which divides the U.S. from Canada. The land includes several islands, and residents must travel by boat in the summer, or by snowmobiles or cars on ice in the winter.
