Stagecoach roads, the opening of the Atlantic and Pacific Railroad and the development of U.S. Route 66 (The Mother Road) were paramount in the rising popularity of petrified wood, in Arizona. The Petrified Forest National Park, created in 1962, was previously the Petrified Forest National Monument, created by President Theodore Roosevelt, using the Antiquities Act of 1906. At the time, Petrified Forest National Monument was the second, out of 18 national monuments, that President Roosevelt created. The first, being Devil’s Tower, in Wyoming.
