What Is The Oldest Mountain Range In North America?

The oldest mountain range in North America is the Appalachian Mountains. The Appalachians began to form about 480 million years ago during the Ordovician Period. They are one of the most extensively eroded mountain ranges on Earth.

The Appalachian Mountains are a vast system that extends over 3,000 miles from Newfoundland and Labrador in Canada to central Alabama in the United States. The mountains encompass parts of eight U.S. states (Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Pennsylvania, Maryland and West Virginia) and two Canadian provinces (New Brunswick and Nova Scotia).

There are three major sections of the Appalachians: the Northern Appalachians; the Central Appalachians; and the Southern Appalachians. The Northern Appalachians include the Green Mountains of Vermont and New Hampshire as well as Maine’s Mount Katahdin –the tallest mountain in northeastern North America at 5268 feet (1606 m). Other notable peaks include Mount Washington –the highest peak in New England at 6288 feet (1917 m)–and Mount Marcy –the highest point in New York State at 5344 feet (1629 m).

The Central Appalachian section includes some of the oldest rocks on Earth as well as some of its most spectacular scenery including Shenandoah National Park with its famous Skyline Drive winding along ridgetops for 105 miles (169 km), Great Smoky Mountains National Park –one of America’s most popular national parks–and Mammoth Cave National Park with more than 400 miles (644 km)of explored caves making it by far the world’s longest known cave system. Notable peaks here include Clingmans Dome -the highest point in Tennessee at 6643 feet(2025m)-and Mount Mitchell -the highest point east of Mississippi River at 6684 feet(2037m).

finally, southernmost section is home to such iconic American landmarks as Stone Mountain-a granite dome that rises 825feet(251m) above Georgia’s DeKalb County-as well Blue Ridge Parkway-a 469 mile long scenic highway that winds through Virginia’s Shenandoah Valley and North Carolina’s Great Smokey Mountains-. Roanoke Island- site of first English settlementin Americas-is also located here.. Notable peaks include Grandfather Mountain -highest peakin Blue Ridge Mtns subrange at 5964feet(1819m)-and Whiteside Mountain -oneof steepest cliffsin Eastern US rising 4000feet(1219m) above valley below-.
