National Parks are part of the heritage of America, and this series examines the most compelling parks in the country. 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. Includes original photos from award-winning author/photographer John Hamilton. ABDO & Daughters is an imprint of ABDO Publishing Company.
