President Teddy Roosevelt used the power given to him in the Antiquities Act of 1906 to declare Devils Tower in Wyoming the first national monument. He thought Congress was moving too slowly and it would be ruined by the time they made it a national park. John Otto, the Colorado National Monument’s first caretaker, watched Roosevelt's actions closely. He, too, believed Congress acted too slowly to protect our nation's treasures, so he kept pushing for action to protect the magnificent canyons forming the southwestern border of the Grand Valley and Grand Junction. Finally, in May 1911, Otto got his wish thanks to a decree from President Taft, and the Colorado National Monument was born.
