Anja Blacha after her success on Mount Everest: “The summit seemed even more littered to me”

A week ago today, German mountaineer Anja Blacha experienced something on Mount Everest that is now a rarity: she had the summit all to herself – because she was the last summit contender of the spring season to reach the highest point on earth at 8,849 meters and was on her way without a Sherpa companion. One day later, the Icefall Doctors declared the season over and began dismantling the ropes and ladders through the dangerous Khumbu Icefall above Everest Base Camp. This deprived Anja of the chance to attempt the neighboring 8,516-meter-high Lhotse without bottled oxygen.

So be it, Blacha can be pleased to be the first German mountaineer and only the eleventh woman in the world to have stood on Mount Everest without a breathing mask. A remarkable achievement that stands out from the almost 800 Everest ascents this spring.

This means that she has climbed twelve of the 14 eight-thousanders – in commercial teams, on the normal routes – without supplemental oxygen. Only Lhotse and Shishapangma in Tibet are still missing from her collection of eight-thousanders. After her safe return from the mountain, Anja Blacha answered my questions.

Anja, first of all, congratulations on your ascent of Everest without bottled oxygen. It was your third summit success on Mount Everest, and you used a breathing mask on the first two. How did you experience the difference – with/without additional oxygen?

Breaking news: Anja Blacha is the first German woman to scale Mount Everest without bottled oxygen

“At the moment, I see it above all as an unbalanced combination of numbers.” That was Anja Blacha’s answer a week and a half ago when I asked her what it meant to her that she had climbed eleven of her twelve eight-thousanders without bottled oxygen. Now she has provided a balanced combination of numbers.

The 34-year-old German adventurer also scaled Mount Everest today without a breathing mask. “She was all alone on the summit,” Mingma Gyalje Sherpa, head of the expedition operator Imagine Nepal, informed me at around 8.30 a.m. Central European Summer Time. According to Mingma, Blacha had climbed to the highest point on earth without bottled oxygen and without a Sherpa companion.

Sirbaz Khan – the first Pakistani to climb all eight-thousanders without bottled oxygen

“I am delighted for Sirbaz that he has now also completed the 14 eight-thousanders ‘topless’,” writes Ralf Dujmovits, Germany’s most successful high-altitude mountaineer. “My heartfelt congratulations to him.”

Sirbaz Khan has fulfilled his self-proclaimed “Mission 14”: On Sunday at 11.50 a.m. Nepalese time, the 37-year-old reached the summit of Kangchenjunga at 8,586 meters with the team from expedition operator Imagine Nepal. Sirbaz also scaled the third highest mountain on earth without a breathing mask. This makes him the first Pakistani to climb all 14 eight-thousanders without bottled oxygen.

Anja Blacha after her Dhaulagiri summit success: “Not in competition with other German female high-altitude mountaineers”

“So, what’s next? Another record-setting expedition? Maybe. As a by-product,” writes Anja Blacha on her website. “Rather than defining my goals based on records, I like to let curiosity guide my way. Following my interests, and living up to my values, virtues, capabilities. The art of striving well. Eudaimonia.” This term from Greek philosophy is made up of “Eu” (good) and “daimon” (demon, spirit). In other words, Anja is trying to live out her own good spirit.

And the 34-year-old German adventurer does this very persistently. This is how Blacha reached the South Pole on skis in the winter of 2019/2020, after pulling her sledge almost 1,400 kilometers from the coast of Antarctica, alone and without outside support.

She has scaled Mount Everest twice – in 2017 via the Tibetan north side and in 2021 via the Nepalese south side. And with her successes on Annapurna I and Dhaulagiri this spring, she has summited twelve of the 14 eight-thousanders in commercial teams via the normal routes – with the exception of Everest, all without bottled oxygen. After her second eight-thousander summit success this season, Anja Blacha answered my questions.

Anja, first of all, congratulations on your 12th eight-thousander. The weather conditions were difficult at first. Then a weather window opened up. How did you experience the ascent and descent on Dhaulagiri?

Jost Kobusch after Everest attempt: “It would have been too dangerous to climb any higher”

Jost Kobusch on the West Shoulder of Mount Everest

Jost Kobusch kept a cool head on Mount Everest. On his first push this winter, the 32-year-old German climber reached an altitude of 7,537 meters on the West Ridge. The altimeter on his watch showed this value on 27 December. His GPS tracker measured the highest altitude at 7,488 meters. On another model, the figure was 7,553 meters. Such differences are not unusual for altimeters.

In any case, Jost climbed around 200 meters higher than during his most successful attempt to date in the winter of 2019/2020, when he turned back on the West Shoulder. This time, he sniffed into the upper part of the West Ridge. I asked Jost via WhatsApp if he hadn’t been tempted to pitch his tent there and climb further up.

Summit success on Cho Oyu – the tenth eight-thousander for Anja Blacha

Now she’s in double figures. Last Saturday (5 October), Anja Blacha and Ngima Dorchi Sherpa scaled the 8,188-meter-high Cho Oyu via the Tibetan north side, her fourth eight-thousander this year – “Ngima with, me without a breathing mask,” as Anja writes to me. “It was a bit windy, but otherwise the conditions were great.”

For the 34-year-old German, it was the tenth of the 14 eight-thousanders, the ninth without bottled oxygen. “I know my body well enough by now to know how it reacts to altitude and that it can usually cope with it. So why not do without this aid if I can?,” Blacha wrote to me at the end of September after her summit success on Manaslu.

Summit successes reported on Shishapangma and Cho Oyu

The first summit successes of the fall season on the eight-thousanders in Tibet are now perfect. The expedition operator Imagine Nepal announced that an eleven-member team led by Mingma Gyalje Sherpa reached the summit of Shishapangma at 8,027 meters today. Five team members had completed their eight-thousand-meter collection, it said: the Nepalese Mingma Gyalje Sherpa and Dawa Gyalje Sherpa, the US-American Tracee Lee Metcalfe, the Japanese Naoki Ishikawa and the Pakistani Sirbaz Khan.

Anja Blacha after her Manaslu success: “I had the summit to myself”

After the eight-thousander is before the eight-thousander. This year, this also applies to Anja Blacha, who has now climbed nine of the 14 highest mountains in the world. This makes the 34-year-old the German woman with the most eight-thousander summit successes.

Last spring, she first scaled Makalu (8,485 meters) and then Kangchenjunga (8,586 meters), both without bottled oxygen. She also climbed without a breathing mask during her successful ascent on Manaslu (8,163 meters) on Monday. Now Blacha wants to try her hand at Cho Oyu (8,188 meters). She answered my questions in Tibet.

Anja, Manaslu was your third eight-thousander summit this year. How did you fare on your ascent?

Anja Blacha after Kangchenjunga success: “Never had such heavy legs on the descent”

Now no other woman from Germany has stood on eight-thousanders more often than Anja Blacha. The mountaineer, who celebrates her 34th birthday on 18 June, achieved a last-minute summit success on the 8,586-meter-high Kangchenjunga, the third highest mountain in the world, at the end of the spring season on the eight-thousanders in Nepal. She had already scaled the 8,485-meter-high Makalu, the fifth-highest of all mountains, on 12 May. On both mountains, Anja climbed on the normal routes, with teams from the commercial expedition operator Seven Summit Treks (SST) and did without bottled oxygen herself.

These were her seventh and eighth eight-thousanders after Mount Everest (in 2017 and 2021), Broad Peak, K2 (both in 2019), Nanga Parbat, Gasherbrum I and II (these three in 2023). Only on Everest did she use a breathing mask on her ascents. This means that the German mountaineer now has one more eight-thousander summit success to her name than Alix von Melle, who has summited seven eight-thousanders to date. Anja Blacha answered my questions after her return from Kangchenjunga.

Congratulations, Anja. You scaled Makalu and now Kangchenjunga at the end of the spring season without bottled oxygen. With eight eight-thousanders to your name, you can now call yourself the most successful German female high-altitude mountaineer. How does that feel?

Norrdine Nouar after Everest attempt: “I can no longer put up with the circus”

Norrdine Nouar listened to his body. On the evening of 22 May, the German mountaineer, who wanted to climb Mount Everest without bottled oxygen and without a Sherpa companion, set off from the South Col at around 7,900 meters. His goal: the highest point on earth at 8,849 meters.

However, the 36-year-old turned back at an altitude of around 8,100 meters. “I realized pretty quickly that I might manage to reach the summit, but that I would never come back,” Norrdine writes to me.

Piotr Krzyzowski: Double ascent of Lhotse and Everest without bottled oxygen

Among the hundreds of Everest summit successes that have been reported in recent days, one stands out: Piotr Krzyzowski from Poland climbed the 8,516-meter-high Lhotse on 21 May without bottled oxygen and without a Sherpa companion.

Instead of returning to base camp, as he had actually planned before the start of the expedition, Krzyzowski climbed from the Lhotse flank to Everest South Col and then on towards the summit at 8,849 meters. On 23 May, Piotr stood on the highest point on earth, barely 48 hours after his summit success on Lhotse. Such a double ascent of these two eight-thousanders without bottled oxygen had previously only been achieved by a handful of mountaineers.

Norrdine Nouar after Annapurna summit success: “I’m still in the eight-thousander learning phase”

Norrdine Nouar on the summit of Annapurna I

Norrdine Nouar has scaled his second eight-thousander without bottled oxygen. Last Sunday (14 April), the 36-year-old German mountaineer stood on the 8,091-meter-high summit of Annapurna I in western Nepal. In spring 2023, Nouar had already scaled the 8,516-meter-high Lhotse. Norrdine did not join any large teams on either occasion, but went it alone – on the normal routes, which were secured with fixed ropes by the commercial teams.

Nouar was a late bloomer when it came to mountaineering. Neither his family nor his friends were drawn to the mountains. He is the son of a native Algerian who came to the former GDR as a guest worker and met his future German wife there. Norrine grew up in the southern German state of Franconia, studied International Technology Management and spent his free time playing computer games rather than going out into nature.

So why did the mountain fever take hold of him at some point? “Ever since I can remember, I have been driven by an insatiable curiosity, a thirst for adventure and the constant urge to take on a new challenge,” Norrdine writes on his website. “I couldn’t help but opt for an uncertain adventure. So I went to the mountains, albeit late.” He reached his first summit at the age of 23. He later climbed four-thousand-metre peaks in the Alps, in the High Atlas in Morocco and also high mountains in the Caucasus and other mountain regions around the world. Nouar has stood on the summits of Mont Blanc, Elbrus and Kilimanjaro, among others. He lives in the municipality of Oberstaufen in the Bavarion region of Allgäu.

After his summit success on Annapurna, Norrdine, currently in Kathmandu, answered my questions.

Norrdine, congratulations on your summit success on Annapurna I. What was going through your mind on the summit?
