In 1906, President Theodore Roosevelt designated the nation's first National Monument and opened the door for all future Presidents to join him in his quest to recognize the diverse depth and breadth of this great nation. Roosevelt's purpose was to preserve significant parcels of American history and geology for future generations to experience. This DVD covers: Devils Tower National Monument, Jewel Cave National Monument and Agate Fossil Beds National Monument. (Each DVD contains a teacher's guide, blackline master quizzes, maps, a timeline and extra historic documents that can be accessed through the computer in PDF format and are opened with Adobe Acrobat.) .
