What stretches about 1200 miles and borders the Blue Ridge Mountains?
Great Appalachian Valley The Great Valley, also called the Great Appalachian Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trough—a chain of valley lowlands—and the central feature of the Appalachian Mountain system. The trough stretches about 1200 mi from Quebec to Alabama and has been an important north-south route of travel since prehistoric times.
Social and economic stratification in Appalachia The Appalachian region of the Eastern United States is home to over 25 million people and covers parts of mostly mountainous areas of 13 states, including Mississippi, Alabama, Pennsylvania, New York, Georgia, South Carolina, North Carolina, Tennessee, Virginia, Kentucky, Ohio, Maryland, and the entire state of West Virginia. The near-isolation of the area's rugged topography is home to communities with a distinct culture, who in many cases are put at a disadvantage because of the transportation and infrastructure problems that have developed.
