PRINCETON – In 1953, when Edmund Hillary and Tenzing Norgay became the first people to reach the summit of Mount Everest, I was seven years old. For a time, I was immersed in the stories of the epic climb. It seemed like an achievement for all of humankind, like reaching the South Pole. Would there still be any frontiers left, I wondered, by the time I grew up?
A photo of the southern summit ridge of Everest has brought these memories back to me. But what a different Everest this is! The splendid isolation of the top of the world has gone. Instead, there is a long line of climbers waiting their turn to stand briefly on the summit.
