Thornton H. Cofield and his wife, Barbara Wittkopf, of Baton Rouge, spent two days in Coober Pedy, Australia, during their September trip through the outback. Here, the couple visits the 'Big Winch,' which sits atop a hill in the town. They also saw an underground opal mine, an underground church and stayed at the Lookout Cave Underground Motel, dug out of the side of a large hill. Coober Pedy is a mining town that produces approximately 70 percent of the world's opals and is located about halfway between Adelaide and Alice Springs.
