They're along the loop trail through the Boogerman Grove in Cataloochee. Should be easy to find--although I stumbled upon them quite by accident. I've since tried to find the faint trail leading to them, but miss it every time. I'm sure a ranger could point you to the place, or someone who knows the area better than I do.
That's really funny, considering that I went to high school in the county and town James Dickey was writing about in DELIVERANCE: Ellijay, Georgia in Gilmer County. I never got the chance to ask James Dickey if he was writing about Gilmer, but I did ask his son, Christopher Dickey who is charge of the Mideast Desk for Newsweek, and he confirmed that I was right.
