The Barberton Greenstone Belt in South Africa is estimated at 3.4-3.6 billion years old, and generally regarded as the world's oldest mountains. Their age is indisputedly older than anything in North America (the Appalachians / Blach Hills / Porcupines / Smokies etc) and only Western Australia lays a possible claim.
Many scientists also believe that the Appalachian Mountains are the oldest mountains in the world. It is possible that the New River is older than any mountain range in the entire world. Finally, the New River's mountain contorting course has exposed rocks that are over 1 billion years old. Fiction- The New River is older than most rivers, but is it the second oldest in the world? There is a scientific argument that the New River might not even be the oldest river in its formation state of North Carolina.
