The Eastern Divide or Eastern Continental Divide (ECD) is a
continental dividein the United Statesthat separates the Gulf of Mexicoand Gulf of St. Lawrencedrainage from the watersheds that flow directly into the Atlantic Ocean.
The Eastern Continental Divide runs from the Triple Divide on an broad hill at coord|41.8465|N|77.8381|W|region:US-PA_type:mountain near the town of Gold in
Potter County, Pennsylvaniasouth of Wellsville, New York, running down the Appalachian Mountains, through Maryland, West Virginia, Virginia, and North Carolina, along the northwestern border of South Carolina, through Georgia and the city of Atlanta, ending at the southern tip of Florida.
The Triple Divide is the hydrologic apex of the Atlantic basin of North America, joining the boundaries of three main drainage systems. From this region the
Genesee Riverbeginning south of Wellsville, New Yorkflows north to the Great Lakesand then the St. Lawrence River. From its source east of Indiana, Pennsylvaniathe West Branch Susquehanna Riverflows southeast, to Chesapeake Bay. The Allegheny Riverbegins its flow east of Coudersport, Pennsylvania, eventually combining with the MonongehelaRiver at Pittsburghto form the Ohio Riverand eventually the Mississippi River. The three systems drain into the Atlantic Ocean at Newfoundland (via the Gulf of Saint Lawrence), Norfolk, Virginiaand New Orleans, Louisiana(via the Gulf of Mexico), respectively.
1760, the Eastern Continental Divide represented the boundary between British and French colonial possessions in North America. France had earlier explored and laid claim to the Mississippi and St. Lawrence drainage areas.
