Could parallel rivers flow in opposite directions? Some rivers have been moving backwards. This got me thinking about an unusual idea.

Could there be terrain that causes two rivers, within a few miles of each other (10?), to flow in opposite directions? One flows east, the other flows west, passing each other by.

Is there anything like this on Earth already? Is it even possible?
One of my favorites: The Columbia and Kootenay rivers. The Kootenay River initially flows southeast, parallel to the initial northwest flow of the Columbia River. The Kootenay passes within 2 kilometers of Columbia Lake, the source of the Columbia.
