I am studying geology this weekend and am finally starting to get a grasp on the formation stages of rivers in the Ozarks. Over the various periods of formation of the Ozarks, the early river courses changed. The rivers across northern Arkansas probably all had a north to south drainage, but changes in elevation and erosion rates in the plateaus altered some to drain in nearly all points of the compass. Thus, we have a few rivers that nearly circumnavigate.
