Probably the North American Divide that I am most familiar with is the Eastern Divide, more commonly called the Appalachian Mountains Divide. For any who do not know the reason why I am so familiar with the Eastern Divide, it is because when I first began full time Wayƒaring, it began by myself traveling overland to Georgia, climbing up a foot path to the top of Springer Mountain where I overnighted in a rustic shelter. After that first climb, I continued my Wayƒaring, (travel on land, at this time in my life, it was specifically on foot) and continued walking for a period of about five and a half months. The footpath was the Appalachian Trail during which I recognized that as I walked northward across the ridge of these mountains, whenever it would rain, in some of the locations, the water that fell to my left side would drain to the west and flow down the creeks, streams, rivers and inevitably flow into the Gulf of Mexico, most of which by means of the Mississippi River. Too, any rain that fell to my right side would drain to the east and inevitably exit the continent into the Atlantic Ocean. This was my very first experience with a water divide, which in this case was the Eastern Water divide. Granted, not all of the Appalachian Trail was on the Eastern Water Divide, but much was.

At its northern terminus, the Eastern Continental Divide originates at Triple Divide Peak, at elevation 2,507 feet (41.846667, -77.837222) in Ulysses Township, Pennsylvania, about 10 mi (16 km) south of the New York-Pennsylvania border, where it meets the St. Lawrence Water Divide. This point divides the eastern United States into three watersheds: those of the (1) Genesee River flowing into Lake Ontario and then the St. Lawrence River to the north; (2) Pine Creek into the Susquehanna River as part of the Atlantic seaboard watershed to the east; and (3) the Allegheny River into the Ohio, the Mississippi, and the Gulf of Mexico to the west.

The Eastern Water Divide, (Eastern Continental Divide, Eastern Divide or Appalachian Divide) is a hydrological divide in eastern North America that separates the easterly Atlantic Seaboard watershed from the westerly Gulf of Mexico watershed. It is one of six continental hydrological divides of North America which define several drainage basins, each of which drains to a particular body of water.

The divide nearly spans the United States from south of Lake Ontario through the Florida peninsula, and consists of raised terrain including the Appalachian Mountains to the north, the southern Piedmont Plateau and lowland ridges in the Atlantic Coastal Plain to the south.

The northern section of the Eastern Divide is found through the interior of the Allegheny Plateau and/or along the Allegheny Mountains. In this northern section, the western drainage flows into the watersheds of the Allegheny River, the Monongahela River and the New River, all of which are tributaries of the Ohio River

Also, all of the eastern drainage flows into the watersheds of the Potomac River, the Susquehanna River, and the James River, all of which flow into Chesapeake Bay before entering the Atlantic Ocean.

The divide's central section follows the easternmost ridge of the Blue Ridge Mountains and thus of the Appalachian Mountains as a whole, and has the geology of high escarpment. In this section, the western drainage of the divide flows into the watersheds of the New River and Tennessee River, both tributaries of the Ohio River.

On the eastern side of this section, the drainage flows into the watersheds of the Roanoke River, Pee Dee River, and Santee River.

Once the Eastern Divide is south of the Appalachian Mountains, this section winds through the lowlands of Georgia and Florida. In this portion, the western drainage of the divide flows into the watersheds of the Apalachicola River, Suwannee River, Withlacoochee River, and Peace River, all of which drain directly to the Gulf of Mexico.

The eastern drainage flows into the watersheds of the Savannah River, Altamaha River, Satilla River, St. Marys River, and St. Johns River.
