The Appalachians & Ohio River Valley Map
In geological and tectonic terms, the map covers only the southern and mid-Appalachians, neglecting Northern New England, Quebec and Newfoundland. From a U.S. perspective, the key northern boundary is the Mohawk River Valley, the only easy route through thier endless folds. The rise to preeminence of New York City was in very large part due to these mountains, as the late 18th and early 19th century growth of the interior was along the rivers that drain them.
This regional map shows the full width of the range and its flanking piedmont and plateau regions, from the Atlantic Coast to the Mississippi. It includes the southern portions of the Great Lakes states, New York, and western New England; most of Mississippi, Alabama, and Georgia; all of Illinois, Indiana, Ohio, Pennsylvania, New Jersey, Kentucky, West Virginia, Virginia, Maryland, Delaware, Tennessee, and the Carolinas.
