Most of the Appalachians is now located within the eastern part of the United States as runoff. Imagine how long it took for huge mountains to erode down and wash outwards into the ocean that distance.

And the Appalachians are still young compared to a few other mountain areas around the world.

Yup. Makhanjwa range in the north west of SA is three times as old as the Appalachians at 3.5 billion years. Days were only twelve hours long back then….

How old is the Australian Great Dividing Range (which has been worn down quite low)

Ed. It's not on the top ten. The Australian old ranges include the Pilbara
