How geography drew the map
Look at the eastern states and you see rivers: the Ohio separates Kentucky from three states to its north; the Mississippi forms all or part of ten state borders; the Delaware, Potomac, Savannah and Sabine each divide two states. Look west of the 100th meridian and you see surveyors: Colorado, Wyoming, Utah, New Mexico and the Dakotas are drawn on lines of latitude and longitude across land that had no obvious natural edges. The Continental Divide, running through the Rockies, is the reason rivers on the map flow either to the Gulf of Mexico and Atlantic or to the Pacific.
