The view looks into Great Onyx Cave at the formation called the Elephant Ear, a large white gypsum deposit. Two visitors stand on a wooden walkway amid draperies of flowstone and stalactites, giving a sense of the chamber's scale. The cave lies within the boundary of Mammoth Cave National Park near Mammoth Cave, Kentucky, and was one of the privately operated show caves in the region.
