Question: The Cullasaja River is a short river that flows from Lake Sequoyah which is fed by Mirror Lake and other creeks and streams originating on the western side of the demarcation of two watersheds of what?

<P0-S0> Hightown is an unincorporated community at the crossroads of U.S. Route 250 and Virginia State Route 640 in Highland County, Virginia, United States. <P0-S1>  Hightown is located approximately 3 mi northwest of Monterey, Virginia. <P0-S2>  The community lies on the division of the James River and Potomac River watersheds, with the main source of the South Branch Potomac River to the north of Hightown along State Route 640 and the source of the Jackson River, a tributary of the James, south of U.S. Route 250 west of Hightown. <P0-S3>  The roof of a barn owned by Jacob Hevener located near Hightown is said to have divided the two watersheds, with rain falling on one side of the roof flowing to the James and on the other to the Potomac. <P0-S4>  The community was originally known as Heveners Store. <SEP> <P1-S0> The Cullasaja River is a short river located entirely in Macon County, North Carolina. <P1-S1>  It is a tributary of the Little Tennessee River (and in turn the Tennessee River, Ohio River and Mississippi River), into which it flows near the county seat of Franklin. <P1-S2>  It originates to the southeast, near Highlands, the county's only other town. <P1-S3>  It flows from Lake Sequoyah, which is fed by Mirror Lake and other creeks and streams originating on the western side of the Eastern Continental Divide, which runs through the east side of Highlands. <SEP> <P2-S0> Brule Glacial Spillway is a Wisconsin Department of Natural Resources-designated State Natural Area that encompasses the valley of the upper reaches of the Bois Brule River. <P2-S1>  This valley was carved by the outlet of Glacial Lake Duluth, which occupied what is now the western portion of Lake Superior, during the retreat of the Superior lobe of Wisconsin glaciation. <P2-S2>  This outlet flowed southwestward through the valley, to what is now the St. Croix River. <P2-S3>  As the glacier melted, and the level of Lake Superior dropped, the direction of flow shifted to its present northeastward course, towards Lake Superior. <P2-S4>  A high point in a vast bog near Solon Springs marks the divide between the watersheds of the Gulf of Mexico and the Atlantic Ocean. <P2-S5>  This divide was used for thousands of years, by Native Americans, European explorers, fur traders, and settlers as a portage between the two watersheds. <SEP> <P3-S0> The Eastern Continental Divide (ECD) or Appalachian Divide or Eastern Divide, in conjunction with other continental divides of North America, demarcates two watersheds of the Atlantic Ocean: the Gulf of Mexico watershed and the Atlantic Seaboard watershed. <P3-S1>  As can be readily seen from the first map at the right, the Gulf watershed demarcated by the Great Divide in red begins along the spine of the mountains of Central America and runs through the American Rockies where is terminates in the triple divide at Triple Divide Peak in Glacier National Park along the U.S.-Canadian border where the Laurentian Divide blocks the waters from traveling south to the Gulf of Mexico.
