It's not about how far north it is its about how far inland it is. How far is it from the great Lakes to an ocean? Now how far is Montana? The Missouri River is the longest in North America on its own before reaching the Mississippi. We are talking about going from the Gulf nearly to Canada.

How far is it from the Atlantic? It's roughly 600km as the crow flies. That's not apples to apples.
