It is undisputed that Adrian Ballinger reached the summit of Mount Everest without bottled  oxygen last Saturday. But a debate rose about how he did it. The trigger was my article about a conversation with Ralf Dujmovits on Monday, two days after his failed attempt without breathing mask on the north side of Everest at an altitude of 8,580 meters. During the satellite phone call, the 55-year-old German climber had accused Ballinger that the American had reported about his ascent in real time via the social networks, but had not mentioned some facts. On the descent, for example, Adrian had been led by an Ecuadorian mountain guide on the short rope, said Ralf. Ballinger’s team responded promptly.

Mount Everest has shown his teeth again on the past weekend – just on the day when eight climbers were on their summit push without bottled oxygen. Contrary to expectations, on Saturday wind gusts and snowfall in the summit area made the ascent difficult. The result: two summit successes without breathing mask on the north side, one on the south side. Two climbers, who used supplemental oxygen at all and reached the highest point at 8,850 meters. And three summit aspirants, who turned back because of concerns for their health.

What a pity! Ralf Dujmovits has not been able to fulfill his dream of reaching the summit of Mount Everest without bottled oxygen. The 55-year-old turned back at an altitude of 8,500 meters. From Camp 3 at 8,300 meters, he telephoned his life partner, the Canadian climber Nancy Hansen. “He had to turn back at 8,500 m because a storm blew in: 40 kph winds with snow. He was losing feeling in his hands and feet,” Nancy wrote on Facebook. “As you can imagine, he is extremely disappointed. The weather just didn’t allow for a summit.” Ralf’s wise decision demands respect and shows that he was still in control of himself.

Ralf Dujmovits is close to his big goal. In his eighth attempt, the 55-year-old finally wants to scale Mount Everest without bottled oxygen. Ralf is only about eight hours of ascent away from the highest point on earth at 8,850 meters – if everything goes well. Today Dujmovits, according to his life partner Nancy Hansen, reached Camp 3 on the Tibetan normal route at 8,300 meters, from where he called her by satellite phone. There had been a thunderstorm for the last hour, Ralf told the Canadian. It had taken him five hours to climb the 600 vertical meters from Camp 2. “He feels a little tired, but he sounds very alert and normal,” Nancy wrote on Facebook. “He will drink a lot now, rest a few hours, and leave for the summit at 1am Nepali time (1.15 pm Friday in Canada, 9.15 pm Friday in Germany).”

So far, the summit attempts of the climbers, who are currently tackling Mount Everest without bottled oxygen, are on schedule (with one exception, see below). According to his life partner Nancy Hansen, Ralf Dujmovits today reached Camp 2 on the Tibetan north side of the highest mountain on earth: “Ralf just called me from 7,700 m, where he will sleep for the night,” the Canadian climber wrote on Facebook. “It is stormy now, but the winds should come down. Tomorrow he will move up to 8,300 m. He feels good!” The 55-year-old has already – as the only German climber so far – scaled all 14 eight-thousanders. Only on Everest in 1992 he had used a breathing mask. The current attempt without bottled oxygen is his eighth and in his own words the “definitely last one” on Everest.

If everything works, there could be a “topless” party on the summit of Mount Everest next Saturday. Some climbers who want to scale the highest mountain on earth without breathing mask have started their summit attempts. Among those who set off from the Advanced Base Camp on the Tibetan north side was Ralf Dujmovits. The 55-year-old, so far the only German who has scaled all 14 eight-thousanders, wants to succeed in his eighth attempt climbing Everest without supplemental oxygen. In his successful attempt in fall 1992, Ralf had used a breathing mask above the South Col, due to bad weather. All other eight-thousanders he had climbed without bottled oxygen. His plan now: today North Col (7,050 m), tomorrow Camp 2 (7,700 m), on Friday Camp 3 (8,300 m) and on Saturday “hopefully towards the summit” (8,850 m), as Ralf writes to me: “I am confident, I feel good and I think that the extremely warm temperatures (probably minus 20 degrees Celsius) might help me.”

It is not only the thin air on Everest that makes climbers pant. Meanwhile, also a race seems to have started to be the most hip in social networks. Number one in this category this spring season – taking in account the media response worldwide – are without question the two Americans Adrian Ballinger and Cory Richards. They document their ascent without bottled oxygen on the Tibetan north side also via Snapchat – the image and video messaging service for smartphones and tablets, in which the messages automatically disappear after a while – and thus make couch potatoes gasp. Under #EverestNoFilter, everyone can follow Ballinger’s and Richard’s ascent via the Northeast Ridge virtually in real time and unfiltered. The two climbers want to reach the 8850-meter-high summit this weekend.

The good weather window on Mount Everest has not yet opened. “Heavy snow in Everest Base Camp at the moment,” American Dan Mazur, expedition leader of the operator Summit Climb, today wrote on Twitter from the Nepalese south side of the mountain. “Our Sherpas are working high up on the mountain, carrying oxygen, ropes, tents, food.”  On the north side of Everest, the Americans Adrian Ballinger and Cory Richards climbed today to an altitude of about 7,600 meters. “For just today, I’m pretty sure Cory and I were the highest people on the planet”, Adrian wrote on Instagram. “Does it matter? Of course not. But it felt special.” The two climbers, who want to scale Everest without bottled oxygen, returned to the North Col, “as afternoon clouds try to cross the border from Nepal into Tibet”. The weathermen expect for the next few days more snowfall on Everest. Maybe one or the other climbers in the base camps on the north and south side will use the time to read again Jon Krakauer’s book “Into Thin Air”. It describes the disaster on Everest in spring 1996. The 20^th anniversary will be next Tuesday .

I have talked to Ralf Dujmovits about Mount Everest then and now. The 54-year-old is the first and so far only German who stood on the summits of all 14 eight-thousanders.

Ralf, you have taken an Everest sabbatical this year. Did you – like many others – want to see how the whole situation on Everest is developing?
