How old are the mountains the section of the Appalachians where I grew up ?
I assumed the entire range was formed in one big event a billion years ago but the Wikipedia article says there were multiple events. I grew up in NEPA near Scranton and I want to know how old the mountains in that area specifically are.
I've found some papers on the "Scranton Rift" but I can tell they are above my pay grade. #science source
