  • Map of Georgia Showing the ‘Gnat Line,’ c. 2000

    The ‘Gnat Line’ is part of ‘a 900-mile escarpment where the Piedmont and Atlantic Coastal Plain meet in the eastern United States. It has traditionally been derived from the abundance of gnats in coastal marshlands and swamps in these states and the relative lack of the insects in the inland regions.’ This imaginary boundary plays a dramatic role in such works as A Man in Full by Tom Wolfe from 1998.
