Shaggy--In addition to books already mentioned, you might want to consider Michael Frome's Strangers in High Places,
Jim Gasque's Hunting & Fishing in the Great Smokies
(recently reprinted), Ken Wise"s Hiking Trails of the GSMNP
if you can find it--it"s out of print and scarce but is far and away the best book on Park trails). Hattie Caldwell Davis's books on Cataloochee, Lanche Holland's Fontana
, and that is just a start. If you are a serious reader there's a 20 or 30 page annotated bibliography in my Fly Fishing in the Great Smoky Mountains National Park: An Insider's Guide to a Pursuit of Passion,
which will give you a much fuller guide to the literature on the region.
