A continental divide is the ridge that geologically separates the watershed boundaries of any continent. In North America, the Continental Divide is the ridge of the Rocky Mountains that separates rivers flowing westward toward the Pacific Ocean from those flowing easterly toward the Atlantic Ocean. It runs from Alaska into Canada and then through Montana, Wyoming, Colorado, and New Mexico in the United States. It continues south into Mexico and Central America along the crest of the Sierra Madre Occidental.
