Content:  Monteregian Hills, which cross the Green Mountains in Quebec, are also unassociated with the Appalachians. ; Central: The central section goes from the Hudson Valley to the New River (Great Kanawha) running through Virginia and West Virginia. It comprises (excluding various minor groups) the Valley Ridges between the Allegheny Front of the Allegheny Plateau and the Great Appalachian Valley, the New York–New Jersey Highlands, the Taconic Mountains in New York, and a large portion of the Blue Ridge. ; Southern: The southern section runs from the New River onwards. It consists of the prolongation of the Blue Ridge, which is divided into the

Title: Geography of Canada
Content:  The Appalachian mountain range extends from Alabama in southern United States through the Gaspé Peninsula and the Atlantic Provinces, creating rolling hills indented by river valleys. It also runs through parts of southern Quebec. The Appalachian Mountains (more specifically the Chic-Choc, Notre Dame, and Long Range Mountains) are an old and eroded range of mountains, approximately 380 million years in age. Notable mountains in the Appalachians include Mount Jacques-Cartier (Quebec, 1268 m), Mount Carleton (New Brunswick, 817 m), The Cabox (Newfoundland, 814 m). Parts of the Appalachians are home to a rich endemic flora and fauna and are considered to have been nunataks during the last glaciation era.

The Appalachian region is generally considered the geographical divide between the eastern seaboard of the United States and the Midwest region of the country. The Eastern Continental Divide follows the Appalachian Mountains from Pennsylvania to Georgia. The Appalachian Trail is a 2175 mi hiking trail that runs all the way from Mount Katahdin in Maine to Springer Mountain in Georgia, passing over or past a large part of the Appalachian system. The International Appalachian Trail is an extension of this hiking trail into the Canadian portion of the Appalachian range in New Brunswick and Quebec.
Title: Appalachian Mountains
Content: Northern: The northern section runs from the Canadian province of Newfoundland and Labrador to the Hudson River. It includes the Long Range Mountains and Annieopsquotch Mountains on the island of Newfoundland, Chic-Choc Mountains and Notre Dame Range in Quebec and New Brunswick, scattered elevations and small ranges elsewhere in Nova Scotia and New Brunswick, the Longfellow Mountains in Maine, the White Mountains in New Hampshire, the Green Mountains in Vermont, and The Berkshires in Massachusetts and Connecticut. The Metacomet Ridge Mountains in Connecticut and south-central Massachusetts, although contained within the Appalachian province, is a younger system and not geologically associated with the Appalachians. 
Title: Appalachian Plateau
Content:  The Appalachian Plateau is a series of rugged dissected plateaus located on the western side of the Appalachian Mountains. The Appalachian Mountains are a mountain range that run down the Eastern United States. The Appalachian Plateau is the northwestern part of the Appalachian Mountains, stretching from New York to Alabama. The plateau is a second level United States physiographic region, covering parts of the states of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Alabama, and Georgia.
Title: Appalachian Mountains
Content:  the mountain range. Most broadly, it refers to the entire mountain range with its surrounding hills and the dissected plateau region. The term is often used more restrictively to refer to regions in the central and southern Appalachian Mountains, usually including areas in the states of Kentucky, Tennessee, Virginia, Maryland, West Virginia, and North Carolina, as well as sometimes extending as far south as northern Alabama, Georgia and western South Carolina, and as far north as Pennsylvania, southern and east central Ohio, Lower New York and the Southern Tier region of New York. The Ouachita Mountains in Arkansas and Oklahoma were originally part of the Appalachians as well but became disconnected through geologic history.
Title: Appalachian Mountains
Content:  The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the Appalachian Highlands physiographic division as consisting of thirteen provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, Saint Lawrence Valley, Appalachian Plateaus, and New England province.<ref name="USGS-Water"> The Appalachians do not include the Adirondack Mountains, a distinct and growing range that is a part of the Canadian Shield and belongs to the Grenville Orogeny. <ref name=peakbag> <ref name=weidensaul>
Title: Appalachian Gap
Content:  The Appalachian Gap is a mountain pass in the Green Mountains of Vermont. The highest point of the pass is located in Chittenden County, about 0.2 mi west of the boundary between Chittenden and Washington County. The pass is in the Camel's Hump State Park. On the east side, Appalachian Gap is drained by Mill Brook, which drains into the Mad River, the Winooski River, and into Lake Champlain. To the west, the gap is drained by Beaver Meadow Brook, which drains into the Huntington River, another tributary of the Winooski River. Lake Champlain drains into the Richelieu River in Quebec, thence into the Saint Lawrence River, and into the Gulf of Saint Lawrence. The Long Trail, a 
Title: Appalachian Mountains
Content:  There are many geological issues concerning the rivers and streams of the Appalachians. In spite of the existence of the Great Appalachian Valley, many of the main rivers are transverse to the mountain system axis. The drainage divide of the Appalachians follows a tortuous course that crosses the mountainous belt just north of the New River in Virginia. South of the New River, rivers head into the Blue Ridge, cross the higher Unakas, receive important tributaries from the Great Valley, and traversing the Cumberland Plateau in spreading gorges (water gaps), escape by way of the Cumberland River and the Tennessee River rivers to the Ohio River and the Mississippi River, and thence to the Gulf of Mexico. In the
