What is the northern most point of the mainland USA?

Answer 1

Northwest Angle, Minnesota (49°23' 4.1"N) is the northernmost point in the 48 contiguous states.

It is a misconception that Maine has the most northernmost point in the Lower 48. However, this is due to the type of map it is. A Lambert Equal-area conic projection, for example, appears to say that the western tip of Washington state is aligned with the northernmost tip of Maine. If you look at a cylindrical projection, you will see that the states bordering Canada west of the Great Lakes are well above the latitude that Maine sits on, and Minnesota has a small triangular tip at the border of Manitoba.
