Each year, millions visit America's national parks. In this series, students will examine the ecosystems, geology, and the flora and fauna that make each park unique. Readers will learn each park's history from early human habitation through its designation as a national park, and examine the conflict between conservation and tourism that challenges efforts to preserve these national treasures for future generations.
