Your National Parks, with Detailed Information for Tourists

A practical, descriptive guide to America's national parks that blends natural history, travel directions, and conservation advocacy. It surveys major reserves such as Yellowstone and Yosemite, explaining geological origins, glacial and volcanic features, thermal phenomena, forests, plant communities, wildlife, and petrified landscapes, while offering practical information on entrances, trails, camps, and administration. The narrative interweaves accounts of early exploration and frontier character with recommendations for responsible development of roads, lodging, and educational facilities, arguing that preserved scenic and wild-life areas serve both public recreation and national benefit.
