Nicholas Clapp

Documentary filmmaker Nicholas Clapp. His new book, "The Road to Ubar: Finding the Atlantis of The Sands" (Houghton Mifflin) is about his search for the lost Arabian city of Ubar. Described in the Koran as "the many-columned city" Ubar, was said to have been destroyed by God for the sins of its people. Using satellite maps to help locate it, Clapp organized two expeditions to Arabia to find Ubar. And he found it in 1992. (Interview by Barbara Bogaev)
