When I was on the Appalachian trail they had a placard that explained it and said it’s also the oldest mountain range in the world, and used to be like 4x the size of the himalayans (which is the youngest.) Others have disputed that, but just internet randos with no sources, I trust the NPS placard.
Hills near me (northern Scotland) were once magma chambers underneath volcanoes! That’s how worn down they are. Wild to think about, and makes some lovely granite.
I find it really cool that the Appalachian mountains used to be connected with what’s now the Scottish Highlands, if memory serves correctly.

So crazy to think about because they’re so worn down at this point. Neat!
