Ahem! The AT *is* a major uplift from the collision of continents. Get
yourself a copy "The Backpacker Magazine Guide to the Appalachian Trail".
There's lots of geologic history information on the AT in there. The entire
first chapter is on the geologic formation of the Appalachian chain and each
of the section-by-section chapters includes a discussion of the geology of
that section. I recommend that book highly to any geology and/or history
buffs. The trail data is out of date but it was general anyway and not
intended as a hiking guide. It's out-of-print but you can find copies
through www.alibris.com, www.bibliofind.com, www.amazon.com or even on Ebay.
