Cutting the old route of the Appalachian Trail from the New River to Damascus along Iron Mountain was one of the most difficult tasks faced by the ATC in its early years. This section of the Virginia was not well mapped and ATC leader Myron Avery had to rely on local knowledge of abandoned roads, forest trails, and hunter's trails to find a usable route between the river and Damascus.

This first page of a much longer letter from Avery to C.S. (Clint Jackson), the Unaka National Forest supervisor in this part of the state, offers some insight into those difficulties. Avery was keen on making sure that his trail guides were precisely accurate and in this letter he says that he seems to be missing an entire mile of trail. The rest of the letter offers two different alternatives for making sense of the route and asks Jackson to weigh in on which one is the correct one.
