Each book features a brief history of the park on its inside back cover and a spot for the official National Park Passport Stamp on the inside front cover.
The insides are Finch Opaque 60#T white graph paper with the rules printed in soy-based “Green Earth” ink, and bound with three copper staples. Use them to plan your route, make your “sights to see” list or record your memories.
Each 3-pack contains three covers as a set, so it is easy to collect all twelve books by purchasing all four sets.
