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 1,200 miles (1,900 km) from Quebec to Alabama and has been an important north-south route of travel since prehistoric times.
