This 1938 map of the Appalachian Trail from the Susquehanna River to the Virginia/Tennessee border, appeared on the back of the stationary of the Appalachian Trail Conference beginning in the late 1930s. It describes those portions of the Trail covered by the PATC's Guide to Paths in the Blue Ridge: Measured Distances and Detailed Directions for 506 Miles of the Appalachian Trail and 65 Miles of Side Trails in Virginia and Adjacent States, originally published in 1931 and reprinted numerous times since. The route of the Trail in 1938, especially in southern Virginia, is quite different from the current route.
