Mac's Pocket Guide: Grand Canyon National Park, Trees, ... (ISBN 1594850275)

Mac's Pockt Guide to Grand Canyon National Park Flowers, Trees & Cacti:
This guide is great. It is small enough to fit into a purse or backpack. It's laminated. Most of the illustrations include more than one part of the plant/tree and states the common name, Latin name, and the measurements of the plant/tree. I look forward to using this guide when I visit the Grand Canyon.
