Edward Abbey (1987 – 1989) was born in Home, Pennsylvania, and lived most of his adult life in the desert southwest, where many of his works are set. He authored the text for Elliot Porter's photographic montage, Appalachian Wilderness: The Great Smoky Mountains. The text is substantial, as coffee table books go. The editors also devoted a significant portion of the text to William Bartram and his book, frequently referred to as Bartram's Travels. The publisher included some of Bartram's original line drawings as illustrations. I have read portions of a copy I obained from a used book dealer and found it delightful.

A list of his books with links and reviews appears on Goodreads.
