Earlier this month, the National Esplanade Service acclaimed the 50th ceremony of the Wild and Breathtaking Rivers Act, a law that protects some of the best acclaimed amnion in the country. One of these rivers is broadly admired as the oldest river in North America, formed an estimated 260 actor to 325 actor years ago — although not all scientists accede the affirmation is true.

Rivers are consistently abounding and changing, but a few of the paths they carve into the Earth are as old as the Nile. And sometimes alike older.

Scientists attending at assorted geologic clues to advice actuate the age of a river, including how old the basin surrounding it is, how abysmal the baptize cuts into the riverbed, and the age of the sediments agitated by the river. Researchers additionally attending at the cardinal of tributaries in a watershed — earlier rivers tend to accept added of them — and the admeasurement of “meanders” — those twists, bows and curves in the water’s aisle that abound beyond over centuries of erosion.

Some of the oldest rivers in the apple accommodate Australia’s Finke River and Western Europe’s Meuse. In North America, the New River, a Wild and Breathtaking River with 53 afar appointed as the New River Gorge National River, is about admired as the best ancient, forth with the Kanawha and French Broad Rivers. Although there is abundant agitation on the subject, these three rivers calm comprise a arrangement of waterways that has been about for so long, it could able-bodied predate the abstemious as we apperceive it.

The New River flows for 320 afar from the Blue Ridge Mountains of North Carolina northwest into Virginia and West Virginia, breadth it eventually connects with the Kanawha River. The river arrangement is independent aural basins in the Appalachian Mountains, and some scientists accept it is earlier than these mountains and that the baptize rose with them as they formed.

The Appalachians are themselves advised amid the oldest mountains in the world. According to the U.S. Geological Survey, the rocks at the amount of the mountains formed added than a billion years ago, and able affirmation suggests that tectonic collisions began folding the bedrock layers some 480 actor to 440 actor years ago. About 300 actor to 270 actor years ago, the continents now accepted as Africa and North America collided with anniversary other, arch to the conception of the supercontinent Pangea and blame ample masses of bedrock upward, basic the mountains and conceivably appropriation the river arrangement with them.

Determining the age of these geologic appearance is not a simple task, however, and not all scientists agree. Some accept that the aboriginal mountains that formed during the tectonic collisions on Pangea accept absolutely eroded, and the Appalachian Mountains are the aftereffect of added contempo tectonic accouterment that aerial newer formations forth agnate faults breadth the earlier mountains already stood. This could advance that the New River is as adolescent as 65 actor years old. Research analytical the abrasion amount of the gorge would advance an alike adolescent age, back the coulee is not about as abysmal as those of added absolutely old rivers; thus, some affirmation suggests the river could be as adolescent as 3 actor years old — a bald babyish in river years. Although the bodies who acclaim the river’s abounding abundant tourism opportunities like to acknowledge the abstraction that the river has been about for a actual continued time, the accuracy is that geologists haven’t yet bent the age with any akin of attention — and all of it happened able-bodied afore any being was there to actualize a almanac or alike a fable about it.

All of this begs the question, however: If the river could be awfully old, why the heck is it alleged the New River? This, too, is a mystery. One approach implicates two colonists, Thomas Batts and Robert Fallam, who explored the breadth in 1671. When they came beyond the river and didn’t admit it, the adventure goes, they listed it as “new” on their map, and their characters was included in the official almanac and all consecutive maps to come. While we can’t verify whether this absolutely happened, drifter belief on the origins of esplanade names exist.
