A thinking person's guide to America's national parks

Not a travel guide, this book is a collection of essays that delve into issues affecting America's national parks and historic sites. The authors, who all have deep personal and professional connections to the national parks, explore how the nation's biological and cultural diversity is represented; the importance of balancing between recreation and preservation; the dynamics of nature as they are shaped by a changing climate; and innovations in technology, sustainability, and stewardship that provide a sense of purpose and hope.
