 Sharp's Appalachia is not a place one can find on a map. It wasn't even a place you could find on the map, really, in 1916. There are accounts of Sharp, for instance, going into isolated settlements in Madison County, North Carolina, encountering a black man on the road and turning away because he thought, OK, if this town is inhabited by African-Americans, I'm not going to find English ballads there. So he didn't bother looking. So he's not interested in capturing a true depiction of the region or its culture.
