PALO DURO CANYON DOCUMENTARY: It's Texas' natural wonder -- what is it? Find out on Passport to Texas. PTT from Texas parks and Wildlife Ken Burns' six-part documentary The National Parks: America's Best Idea airs on PBS stations nationwide this fall. Inspired by Burns' series, Amarillo's PBS affiliate, KACV-TV produced a one-hour documentary The Natural Wonder of Texas: Palo Duro Canyon, set to air September 12. :08 -- We're going to try and hit the highlights. And hopefully, people will see that small part of it and do some research of their own, or come visit the canyon. Marcie Robinson is a producer at KACV-TV. She says viewers will experience this magnificent, historic canyon from the ground up. :37 -- We delved really, really deeply into the geology of Palo Duro Canyon; the lowest layer of the canyon is 250-million years old. And then on into the Indian, early civilizations, primitive Indian cultures. And then, into the Apaches, Comanche, Kiowa, Cheyenne. And then, another thing I had no idea about was that the CCC, during the depression, built a road into the canyon, and built cabins in the canyon, the El Coronado Lodge, and most of the buildings that you see now that people use in the Palo Duro Canyon were built by the CCC during the depression. Once The Natural Wonder of Texas: Palo Duro Canyon airs locally, it will be available for all Texans to enjoy on the KACV-TV website. We have a link to it on our website, passporttotexas.org.
