The pictures in the book are not as striking as more modern photographs due to the advances in digital technology and photography. However, they are good enough to complement a wonderful piece of writing. The author includes beautiful descriptions of the Okefenokee landscapes, flora, and fauna, and he mixes in a lot of interesting aspects of the human history associated with it. Well worth reading for those that dream of adventure or have a love for nature, particularly the Okefenokee Swamp.
This book is on the American Wilderness shelf of my home library. I enjoy the photography by Patricia Caulfield, and now I take time to read the text by Franklin Russell. The well-written text made this area appealling until I really consider how much I hate mucking about in land so difficult to travel across that is filled with mosquitoes. I recommend this book for all armchair travelers.
