The Central Pangean Mountains were a great mountain chain in the middle part of the supercontinent Pangaea that stretches across the continent from northeast to southwest during the Carboniferous, Permian Triassic periods.
The Appalachians have had 3 orogenic (mountain building) periods followed by significant erosion. What you see currently is the result of the last erosional period. Imagine something much closer to the Himalayas (similar continental convergence process) at their highest. Appalachian geology is rather complex compared to other mountain ranges. The Rockies aren’t quite comparable since they formed due to eastward migration of a shallow angle subducting plate. Trust me, I’m a geologist.
