Maine

Lake of the Woods, Minnesota is the northernmost point in the contiguous United States because of the Northwest Angle.

Yes, Michigan is farther north than Maine. The "Maine" reason (sorry I couldn't resist) this is surprising is due to map distortion. When we look at a map of the united states we commonly view it flat either on a screen or on a paper map when in fact the actual geography is not flat. The Earth is round, so when we try to make a round object flat the image is distorted, especially around the edges. Maine actually goes more east than it does north. We also need to keep in mind that the earth is tilted at a 23° angle, so from the angle we normally see Earth, the northern most latitude line of Michigan doesn't quite touch Maine. So yes, Michigan is farther North than Maine, it just doesn't look like it would be when looking at a map.
