Back in the day, the trail was frequently relocated. Guide Books were published maybe once every 5 years, so the ATC would publish trail relocations in the May edition of the Appalachian Trailway News. The name changed in 2005, so you might find old copies in the library. Also a mileage fact sheet would be printed annually. Between these resources you could get a sense of the trail route.
On June 30th, 1974, an "off the road relocation caused some grief today." The previous day we crossed the Nolichucky River Gap and ate black berries and blue berries along the trail.
I also discovered that I didn't care for Lemon Instant Pudding. Pudding became a regular dinner items and the instant version just needed powdered milk and water to make. I already carried powdered milk for my breakfast granola.
Here is a shot of Curley Maple LT a few miles north of the Nolichucky.
It has been replaced and I suspect the trash barrel is no longer there because of the LNT movement.
