Geography Notes: When dinosaurs roamed the earth, this part of the continent was at the bottom of a shallow sea. Since then, immense tectonic power has lifted all this land out of the water and raised it to as much as 4,000 feet in elevation; and the sea is 500 miles away.

With three sets of named hills on the Essential Geography; Red, Smoky and Flint, Kansas has more relief than its reputation asserts.
