On the centennial of the National Park Service, this richly illustrated book offers invaluable advice on exploring America’s national park system. The book delves into issues affecting an array of parks: the iconic western national parks like Yellowstone; the urban parks such as Golden Gate National Recreation Area; historic sites including the Statue of Liberty National Monument and Gettysburg National Military Park; and cultural areas like Mesa Verde National Park that are among America’s over 400 national parks. Twenty-three essays from contributing authors with deep personal and professional connections to the national parks serve as expert guides to places in the park system where: much of the nation’s biological and cultural diversity is represented; ideas such as freedom, civil rights, and conservation were conceived; vast wilderness offers solitude and reflection; storied landscapes preserve a sense of place; the balance between recreation and preservation is tested; research and learning engage the next generation; the dynamics of nature are being shaped by a changing climate; and innovations in technology, sustainability, and stewardship provide a sense of purpose and hope.
