The flight crosses the Appalachian Mountains (visible around 1.5 hours out, appearing as a series of parallel ridges running northeast-southwest), the Ohio River valley near Cincinnati, and transitions into the flatter terrain of Kentucky and Tennessee. The Mississippi River is visible around the 2.5-hour mark as a major brown ribbon.
