This area includes 3 major National Parks (Yellowstone, Grand Teton and Glacier/Waterton), plus a host of mountain ranges – from the Wasatch and Uintas of Northern Utah to the Canadian border. Almost 100 beautiful species have been chosen to illustrate the enormous range of colors and forms that are to be found from the valleys up to almost 14,000 feet. Vivid color photographs are supplemented by text describing key features such as size, habitat and blooming period. A companion guide to the Southern Rockies almost doubles the number of species, many of which are found in both regions.
