I did the Rock Castle Gorge Loop off of the Blue Ridge Parkway in Floyd County a couple of weekends ago (a great hike, by the way, should -- Heaven forbid -- you want a break from the AT) and passed by the old Rocky Knob Shelter. It apparently dates back to the days when the AT followed the eastern Blue Ridge through southern Virginia rather than heading into the Alleghenies south of Roanoke. The re-route must have occurred sometime after the 1940s because Earl Shaffer purportedly stayed at Rocky Knob during his famous first through-hike. My question is: Does anyone know the route that the AT originally took around Roanoke and points south? I am guessing it was close to the current Parkway route, but, then again, maybe not. And, if no one knows the answer, does anyone know how I might go about finding the answer?
