"THIS IS THE FIRST TIME I've seen it like this," says Onzchhu Sherpa, 31. Starting on the night of May 18 and going through the 20th, roughly 300 climbers, guides, and Sherpas crowded onto the upper slopes of Everest's Southeast Ridge. From the 19,000-foot shoulder of a neighboring peak, where I was watching, Everest appeared to be lit up like a Christmas tree with the headlamps of climbers converging from the mountain's north and south sides.
