    What could possibly cleave the continent more than the Grand Canyon? In many places it’s a barrier that can’t be crossed except by flight.

    It’s a prominent river until Yuma, AZ, which is not too far from the Gulf of California. And even if the water doesn’t always flow, it forms the boundary between the Mexican states of Baja and Sonora.

      Yes, but you fail to understand the difference between a peninsula and a psuedo-island (a piece of land entirely surrounded by any body of water, artificial or manmade).

      The Colorado River starts in Colorado is does not flow over the continental divide.

        No river can be traced all the way up to a dividing ridge. As the contributing drainage area gets smaller it will be a stream, then creek, trickle, gulley, and by the time it’s on a mountain ridge it’s nothing.
