This directory offers a comprehensive outdoor education reference source on more than 4,700 parks, forests, wildlife refuges, and recreation areas administered by the National Park Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and by state park agencies. The Directory provides alphabetized, descriptive information on each unit, including facilities, activities, and special features, as well as important reference information (including address and phone number). Also included is coverage of lesser known areas, located away from principal highways, that contain scenic and cultural resources of comparable quality to the more famous parks. The volume is divided into seven main sections that include: (1) national parks (51); (2) national forests (148); (3) national wildlife refuges (364); (4) national trails (19); (5) state parks (3,338); (6) urban parks (155); and (7) park- and conservation-related organizations. The introduction provides a discussion of park nomenclature and a classification of the different types of parks. Fifty state maps, four national maps (parks, forests, wildlife refuges, and trails), labeled samples of national and state park entries, and an explanation of the indexes are included. (LL)
