This is Pettit tunnel, just south of Clinchco and Squirrel Camp tunnel (so named, it’s said, because squirrel was about all the tunneling crew had to eat while they worked there). It sports a 1928 dating. Nice, sensible tunnel, 379′ long at 37.133940, -82.369548, just off Highway 63 (revisited). This was one of those “Well, here it is. Take a picture. Okay, what’s next?”. Next is Caney Fork tunnel, that’s what. Squirrel’s actually pretty good, btw. Mom used to make a killer fried squirrel with gravy.
