The Continental Divide

Updated July 10, 2020 | Infoplease Staff

The Continental Divide is a ridge of high ground that runs irregularly north and south through the Rocky Mountains and separates eastward-flowing from westward-flowing streams. The waters that flow eastward empty into the Atlantic Ocean, chiefly by way of the Gulf of Mexico; those that flow westward empty into the Pacific. Every continent with the exception of Antarctica has a continental divide.
