Mount Everest has gotten so crowded that climbers are perishing in the traffic jams

Many teams had to line up for hours on May 22 to reach the summit, risking frostbites and altitude sickness, as a rush of climbers marked one of the busiest days on the world's highest mountain. PHOTO: AFP

KATHMANDU (WASHINGTON POST) - Anjali Kulkarni, an Indian mountain climber, trained for six years to make it to the top of Mount Everest, the highest mountain peak in the world. She finally fulfilled her longtime goal when she reached the summit this week. But it was the descent that killed her.

Her son, Shantanu Kulkarni, told CNN that she died after getting stuck in a "traffic jam" on the mountain.

"She had to wait for a long time to reach the summit and descend," Thupden Sherpa, who organised tours on the mountain, told Agence France-Presse.

"She couldn't move down on her own and died as Sherpa guides brought her down."

Two other Indian hikers, Kalpana Das, 52, and Nihal Bagwan, 27, also died this week.

Keshav Paudel, who organised tours on the mountain, told AFP that Bagwan was "stuck in the traffic for more than 12 hours and was exhausted".

They are among the at least 17 people to have died climbing in Nepal's Himalayan mountains this season, including at least seven on Everest in the past week, as a few days of clear weather attracted huge numbers of climbers hoping to scale the 29,029 feet to the mountain's peak.

Nepal has issued around 380 permits for those hoping to climb the mountain, AFP reported. They cost about US$11,000 (S$15,100) each, and hikers are accompanied by local, and sometimes international, guides.

A chilling photograph from the mountain shows a long line of mountaineers queuing to ascend a steep ridge to the summit. The photo was shot by Nirmal Purja, an avid mountaineer, who wrote in an Instagram caption that he estimated there were 320 people in line.

Traffic jams create dangerous situations for climbers, who are often already exhausted and carrying heavy loads while battling altitude sickness, which can make people dizzy and nauseated.

Gordan Janow, director of programs at Alpine Ascents International, has been organising treks to Everest for around 30 years. He said overcrowding often occurs, but "every year seems to be worse and worse".

When a line starts to back up, "you're changing your natural pace so you're spending more time in this high altitude zone than might be necessary if you were climbing 10 to 15 years ago," he said.

Alpine Ascents currently has a group of a dozen climbers on the mountain, he said. And one of the most important skills for the guides who accompany them, he said, "is knowing when to turn people around".

"The idea isn't to push yourself to the ultimate maximum to reach the summit," he said. "Then there's no steam or energy left in your body to get down."

Everest attracts climbers from around the globe, and the victims come from a diverse set of backgrounds: Séamus Lawless, an assistant professor of computer science at Trinity College in Ireland, went missing last Thursday when he slipped and fell shortly near the summit, on a different side of the mountain from where the main traffic jam is taking place.

On Friday, the Independent reported that a second Irish climber, Kevin Hynes, died on Friday. He had climbed parts of Everest before, and the British group he travelled with, 360 Expeditions, said in a statement he was "one of the strongest and most experienced climbers on our team".

Earlier this week an American, Donald Lynn Cash, 55, of Utah, died after falling sick, possibly from the high altitude. It was unclear what role, if any, the foot traffic jams had in his death.

And a 65-year-old Austrian man is also among the dead.

Last year, 807 people reached the mountain's summit, more than had ever reached the top in a single year before. When climbers choose to scale Everest, they do so with the understanding of the potential perils they could encounter along the way.

In addition to the risks of altitude sickness and exhaustion, there have been a number of avalanches on the mountain over the year, including one set off by the catastrophic 7.8 magnitude earthquake that struck Nepal in 2015. In that instance, an avalanche swept down the mountain and through the base camp, killing at least 18 people and injuring dozens more.

Still, most who make the trek expect to come home.

Cash, who took a sabbatical from his executive job at BMC Software to finish scaling the world's seven highest peaks, wrote on LinkedIn before his trip that he was "excited to look for the next chapter of my career in June when I return. Safely. With all my digits."

Instead, his body will remain on Everest.
