KATHMANDU, Nepal — Climbers on Friday found the body of one of two Indians who went missing near the top of Mount Everest, while a helicopter brought back the body of an Australian woman who died on the mountain. Worsening weather was forcing everyone to descend to safety, with the last missing climber presumed dead. The discovery of Paresh Chandra Nath’s body brings the official Everest death toll this year to four.
