KATHMANDU, Nepal—The body of an Indian climber was spotted on Mount Everest on Monday, the fourth fatality during a busy and tragic weekend on the world’s highest peak.

Sherpa rescuers spotted the body of Indian climber Ravi Kumar, but it was impossible to retrieve the body, said Thupden Sherpa of Arun Treks and Expedition. It appeared that Kumar had fallen some 650 feet below the route, he said.

Climbers from the United States, Slovakia and Australia also died on the mountain over the weekend. Because of bad weather conditions, climbing to the summit had been delayed this year, leading to a rush in the last few days to get to the summit.

Kumar, 27, became ill on his descent Saturday and did not make it to the nearest camp, though his accompanying Nepalese Sherpa guide did reach camp. The guide also was sick but managed to drag himself to the camp at South Col, located at 26,247 feet.

Kumar and his guide reached the 29,035-foothigh summit at about 1:30 p.m. Saturday, which is considered late, and not many climbers were around when they were returning.

Tourism Department official Kamal Prasad Adhikari confirmed that American climber Roland Yearwood, 50, from Georgiana, Alabama, died Sunday, but it was not clear if or when his body would be brought down.

A Slovak climber, Vladimir Strba, 50, also died on Everest on Sunday, Tourism Ministry official Gyanendra Shrestha said. His body was brought to the South Col camp.

Australian climber Francesco Enrico Marchetti, 54, from Queensland, died on the Chinese side of Everest, according to the Himalayan Times newspaper. Other details were not available.
