Jon Krakauer Discusses the Death of Eight on Mount Everest.

Krakauer is the author of the book Into Thin Air, about the disastrous 1996 Mount Everest climb in which eight climbers were killed. His new book, Under the Banner of Heaven: A Story of Violent Faith, is about Mormon fundamentalism and the story of the two Lafferty brothers who murdered a woman and her infant daughter because they say that they had received a revelation from God to do so. Krakauer reports there are some 40,000 Mormon fundamentalists in the American West, Canada and Mexico. The Mormon Church does not recognize fundamentalists as part of their faith.

Writer Jon Krakauer. Jon Krakauer is a contributing editor for Outside magazine, and the author of "Into the Wild" [Villard Books]. "Into the Wild" tells the story of a young man's rash and tragic journey into the Alaskan wilderness. Christopher Johnson McCandless gave away all his money to charity, abandoned his car and possessions, hiked into the woods and within four months had starved to death.

Sherpa guides are 10 times more likely to die than commercial fishermen, the most dangerous, nonmilitary occupation in the U.S. But they're offered little financial protection by companies who charge Western climbers thousands of dollars for a trip up the mountain.
