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.
Hundred-Mile Wilderness The Hundred-Mile Wilderness is the section of the Appalachian Trail running between Abol Bridge just south of Baxter State Park and Monson in the state of Maine. It is generally considered the wildest section of the Appalachian Trail, and one of the most challenging to navigate and traverse. This section of the A.T. is crossed by several logging roads and is maintained by the Maine Appalachian Trail Club. It consists of a small corridor of protected wilderness surrounded by large tracts of public and private land controlled by paper companies. An increasing amount of the adjoining lands are being protected by groups like the Appalachian Mountain Club and the Nature Conservancy.
