This wildflower book has been in publication since the 1950s. Three generations of backpackers have relied on it for accurate information and beautiful full color pictures that make it easy to identify the varied species of flowers growing profusely throughout the parks, especially those found along roadsides and hiking trails. The current edition has updated botanical information and plant descriptions that tell where and when to look for the plants as well as historical and cultural uses. Dr. Richard J. Shaw was a professor of botany at Utah State University for thirty-nine years and a seasonal naturalist for Grand Teton National Park, where he spent thirty-one summers studying the plants and wildflowers of the Greater Yellowstone Ecosystem.
