This now reminds me of the effect you get when paddling down the Nahanni
River downstream from the Virginia Falls.  The cliffs on either side of the
river show the layers of sedimentary rock slightly sloped relative to horizontal.
This makes the river appear sloped.  An optical illusion like those magnetic
hills.  

Definitely a possibility with the right shoreline.

Three candidate explanations - ready for a vote? :-)
