On June 1, 1925, a 315-car caravan led by Governor George Dean arrived at the Red Canyon tunnels to celebrate the opening of Utah National Park, later renamed Bryce Canyon National Park. A flower-strewn gate closed the entrance to the second tunnel, a banner proclaimed "Welcome to Utah's Fairyland," and children dressed as fairies tied flowers and long ribbons to the bumper of the governor's car. After the governor declared his belief in fairies, two young elves opened the gates, a band perched atop the tunnel began to play, and dancing fairies pulled on the streamers while men pushed from behind to draw the car through the tunnel. Ever since that celebration, the Red Canyon tunnels have served as an entrance to Red and Bryce Canyons. The road through Red Canyon had been a dream of Powell National Forest Supervisor W.J. Humphrey since his first visit to Bryce Canyon around 1915, and after nearly a decade of effort he achieved it. The bright formations of Red Canyon are largely limestone formed from sediment in a lake that covered the region 35 to 50 million years ago, and their pink, orange, and red colors come from oxidized iron in the limestone.
