Query: Compact & Comprehensive. A Must Have Guide!

If you could only take one nature field guide this book is the one. I surprisingly found almost every plant, bird, insect, animal, ect, that I encountered, on a recent trip, in this book (some weren't even listed in the dedicated guides). The book also has sections on topography, geology, habitats, astronomy, weather and conservation.It is beautifully put together with sharp, clear color photography. I don't know how they managed to get so much in this pocket guide. It's another wonderful book by Knopf and a great gift for nature lovers and hikers (No, I don't know or work for the publisher). I'm only on this site to buy another copy for a friend. Enjoy!
