On May 28, 2026, three elite Latvian mountaineers died on Mount McKinley (Denali) after a catastrophic fall on a section called The Autobahn — the deadliest stretch of the West Buttress route, responsible for more fatalities than any other single section on the mountain. This is the full story of the Latvian national expedition: seven of Latvia's best high-altitude climbers, 14 days into a flawless ascent of North America's highest peak, less than 2,000 feet from the summit — and how a 45-degree ice slope less than a mile wide destroyed the expedition in minutes. We break down the Swiss cheese model of disaster: altitude sickness and impaired judgment at 17,000 feet, unprotected falls on hard blue ice, roped team cascade failures, and the brutal history of Denali climbing accidents that the Park Service has been documenting since 1980. If you're interested in mountaineering disasters, Denali expeditions, high-altitude survival stories, or true survival documentaries, this is the story you need to know.

May 28th, 2026. North America's tallest mountain, deep in the Alaska range. No road reaches its
base. Fourteen days into their climb, a team of seven Latvian mountaineers had less than
2,000 feet left to go. At midnight, the park service received a distress call. Three of them
were gone. Not in the Caucasus, not on the slopes of the Himalayas. These climbers had spent years
earning their way to a mountain like McKinley. They came from Latvia, a country roughly the size
of West Virginia that had already sent mountaineers to the summit of Everest and the highest peaks in
Nepal. The Latvian Mountaineering Association had assembled seven of their finest. In Latvia's
tight-knit climbing world, a team like this had only one name. They called it the National
Expedition. But three of them never came back. The part that bothers me with this story is that
these were experienced vetted mountaineers on the most traveled route on the continent.
They had every reason to succeed, and then a slope shorter than five football fields laid
end-to-end destroyed the expedition in minutes. It wasn't just one mistake. It was a chain.
Welcome to tourist tragedies. Mount McKinley stands at 20,310 feet above sea level. That is
nearly four vertical miles. It is the highest point of the North American continent and,
measured from base to summit, one of the largest vertical rises of any mountain on Earth.
Every year, somewhere between 1,000 and 1,200 people attempt to reach the top. Less than half
of them succeed. And that number includes some of the world's most experienced mountaineers.
The mountain does not care about resumes. The West Buttress is the standard route,
the one most climbers take, and the one described in every guidebook as the most accessible path
to the summit. But accessible on McKinley is a relative word. The route crosses crevassed
glaciers, exposed ridges, and high-altitude snowfields that demand weeks of acclimatization,
careful logistics, and a team capable of making life or death decisions when the oxygen in the
air is less than half of what you breathe at sea level. The seven Latvians who departed on May 14
had done everything right. They were formal members of the Latvian Mountaineering Association.
An organization whose members have been reaching some of the world's most technically demanding
peaks for decades. They had the credentials, the equipment, and the team experience to be
exactly where they were. And honestly, when you look at how far they had come,
you'd probably agree they were the last people you'd expect to fall.
How does a country like Latvia produce serious high-altitude mountaineers?
That question has a very specific answer. And it starts in 1991.
When Latvia regained independence from the Soviet Union, a climber named Teodoras Kirsis
did something that seemed almost impossible for a nation of under 2 million people.
He began systematically going after the world's highest peaks. In 1993, he and his team reached
the summit of Daulagiri, an 8,000-meter peak in Nepal that has killed dozens of climbers
across its history. Two years later, on May 14, 1995, Kirsis and Eman Zolz became the first
Latvians ever to stand on top of Everest. By 2001, Kirsis had completed the Seven Summits,
the highest peak on every continent. In a country roughly the size of West Virginia,
that is the equivalent of a national hero. The Latvian climbing community is small.
At any given time, there are perhaps a few hundred people in the entire country
who climb seriously, and a much smaller number who pursue high-altitude expeditions at the level
this story involves. It is a tight world. Climbers know each other, they train together,
and when a formal expedition is assembled under the banner of the Latvian Mountaineering Association,
the selection process carries real weight. You do not get onto one of these teams by signing up,
you earn it. The McKinley Expedition was exactly that kind of undertaking. Seven people,
a fixed departure date of May 14, a summit target of June 11, a 28-day window to climb 20,000 feet
up the most remote mountain in North America and return safely. There is one more detail
about that departure date worth noting, May 14, 2026. Exactly 31 years before, on May 14,
1995, Cursus had stood on top of Everest for the first time. Whatever the coincidence means,
the Latvian climbing community would have known it.
How do you measure the caliber of the people assembled? One name from the survivor list
offers a clue. Valdis Purins, one of the three who stayed at camp that night,
is described by Latvian media as one of the country's most experienced alpinists,
with documented ties to Cursus' own expedition community. If someone of that caliber was on
this team, that tells you something about the standard every other member had to meet to be
included. This was not a recreational trip, this was a mission, and for 14 days, it was going
as planned. The West Buttress route starts at Kahiltna Base Camp, 7,200 feet above sea level,
on a glacier so vast and flat that bush pilots call it the football field of Alaska. You fly
in by small plane from the town of Talkeetna, a 45-minute hop over a landscape so remote that
the words road and town simply stop applying somewhere over the Alaska range. From Kahiltna,
the route climbs through five successive camps, spread over roughly two weeks of upward movement.
Camp 1 at 7,800 feet. Camp 2 at 11,000 feet. Camp 3 at 14,000 feet, where the altitude begins
to register, not as a number on a map, but as a physical fact. A weight in your lungs,
a slowness in your limbs, a strange deliberateness that settles into every small action.
And then High Camp, 17,200 feet, the last livable outpost before the upper mountain.
Here is what 17,200 feet actually feels like. It is higher than every summit in the Alps,
higher than any point in Europe, Africa, or Antarctica. At that altitude, experienced
mountaineers describe the act of lacing a boot as something that requires conscious,
deliberate attention. Not because the fingers don't work, but because the brain is running on
partial power, and simple tasks suddenly demand complete concentration. Think about that for a
moment. These people were functioning, moving, and making decisions in conditions where most
people cannot complete basic tasks without stopping to breathe deliberately between each step.
They had trained for exactly this. The Latvian team had been moving well. They had started May
14th, and by the 28th they had completed the long climb to High Camp on schedule.
Every altitude gain on McKinley is a negotiation. Your body wants to slow down. The mountain
demands patience, and the weather can cancel everything in an afternoon. The fact that all
seven had reached 17,200 feet meant they had already beaten the mountain's most patient opponent.
Time. Summit pushes on McKinley typically begin from High Camp in the very early hours of the
morning, two or three in the morning, when the snow surface is coldest and firmest,
and the risk of a surface slide is at its lowest. Teams ascend the upper slope to Denali Pass at
18,200 feet, then follow the high ridge toward the summit. On a clear day from the pass,
the top of North America looks almost close. It never is. The team's summit target was June 11th.
They were on schedule, positioned correctly, and moving well at an altitude where most people are
simply trying to stay warm. The entire arc of the expedition, the planning, the selection,
the weeks of climbing, the careful acclimatization had brought them to this moment.
Fourteen days of progress, less than 2,000 feet left. Life was, quite simply, perfect,
and then four of them stepped onto the Audubon. May 28th. High Camp. 17,200 feet. The sky above
the Alaska Range that morning was clear. The temperature at that elevation was well below
freezing, and the overnight cold had done what overnight cold always does to snow at altitude.
It hardened. Not powder. Not grippy, reliable neve. Hard, compacted ice. The plan was
straightforward. Four of the seven would ascend the Audubon to Denali Pass, gain 1,000 feet of
elevation, and establish position for the final summit push. Inize Pucheka, Vija Olte, Renard's
Koenig Salaks, and Martin's Bilzens. The three who stayed behind were Valdez Purin's, Edgar's
Above high camp, the world narrows. The route becomes a single question. Up. The sky at that
elevation carries a shade of deep blue you do not see at lower altitudes. The air is thin enough
that conversations happen in short bursts between deliberate breaths. Every placement of a crampon
is intentional. The Audubon rises roughly 1,000 vertical feet over the course of less than a mile
of horizontal ground. That does not sound dramatic, but the angle is 45 degrees, and the
surface, hardened by cold overnight temperatures, was not the soft powder that gives climbers grip.
It was ice. On hard blue ice at a 45 degree angle, a crampon either bites or it does not.
There is no middle ground. The Park Service has been documenting this for decades.
Their official guidance specifically warns that conditions on the Audubon can vary from deep snow
avalanche danger to hard ice, and that climbers should be prepared to place their own protection
as needed. That sentence is worth pausing on. It means the fixed protection, the metal snow
pickets and anchors that rangers and mountain guides hammer into the snow along the route,
is helpful, but it is not continuous. It does not cover every meter of that slope,
and above a certain point you are moving through terrain where the fixed protection runs out,
and you are responsible for placing your own. The four Latvians knew this. They had been trained
for exactly this. But somewhere on that slope, something gave way. To understand what happened
next, you need to understand what the Audubon actually is. The name comes from a group of
German climbers. The story passed around by guides on the mountain for decades is that a team slipped
on the traverse and, in the dark humor that the high altitude community tends to favor,
someone watching from below noted that they moved very quickly. The Audubon. The name stuck.
That dark humor has a very serious number behind it. According to the National Park Service,
the Audubon has been the site of more fatalities than any other single section of the West
Buttress route. Since 1980, a span of 46 years before this accident, at least 14 people had died
in falls along this stretch alone. On a peak where more than 130 climbers have died across
all routes and all time, the Audubon is responsible for a disproportionate share.
The reason is physics. A 45 degree slope of hard ice behaves almost like a ramp.
If you're crampon, the spiked metal plate attached to your boot for traction,
fails to bite into the surface cleanly, you do not stumble, you slide. And on hard blue ice,
a slide accelerates almost immediately. Without something to arrest it, either your ice axe driven
hard into the slope within the first critical seconds, or a fixed anchor you are already
clipped into, a fall on the Audubon has nowhere to go but down. Down on that section means a
1,000 vertical feet. 1,000 feet is roughly the height of the Chrysler building in New York.
Falling that distance on a 45 degree ice slope without arresting it in the first few seconds
is not survivable. The Park Service and mountain guides place snow pickets at fixed intervals along
much of the route, metal stakes hammered into the snow, to which climbers clip with carabiners.
But the pickets do not cover every meter, and as the route rises toward Denali Pass,
the fixed protection becomes sparser. Climbers are expected to supplement it with their own.
That is the terrain these four people were on. Somewhere on that slope, one of them fell. The
rope went taut. And then there were four people falling, instead of one. The Audubon does not
slow you down. It does not catch you. It offers 1,000 feet of open ice, and nothing else. What
sound that made? Only three people alive? No. At approximately midnight on May 28th,
rangers at Denali National Park and Preserve received a distress call.
Four climbers had fallen on the Audubon. The three who stayed at Camp, Purins, Madzoulis,
and Svarins had reached their teammates. Three were not responding. The fourth,
Martins Bilzens, was alive. The exact sequence of how four people came off that slope
is not yet fully known. High-altitude accident investigations take time,
require cooperative weather, and demand careful forensic work. The Park Service,
following standard protocol, does not release detailed cause information until 72 hours after
notification of next of kin. What the evidence does confirm is this. Bilzens was found alive
at or near 17,200 feet, approximately 1,000 feet below, where the fall likely began.
He had survived something the others had not. The rescue operation launched immediately.
Getting a helicopter to 17,200 feet on McKinley is not routine. The air is thin enough that
rotor blades struggle to generate lift. The terrain does not allow landing. Rescuers deployed a long
line, a rope suspended beneath the aircraft, and extracted Bilzens directly from the slope.
He was airlifted to K. Hiltna Base Camp and transferred to an air ambulance. He was in
critical condition. Inez Puchayka, Via Olte, and Renars Kuniksalaks were beyond rescue.
The Park Service announced on Friday that operations for the three remaining climbers
had transitioned from a search and rescue mission to a recovery effort.
Valdis Purins, Edgars Medzoulis, and Guntis Svarins did not leave the mountain. They waited
at 17,200 feet, in air half as thick as sea level, until rescuers arrived. Two of the three suffered
frostbite during the wait. Doctors who later examined them expressed cautious hope that
their hands would retain full mobility. On Friday, May 29, the Latvian Mountaineering
Association issued a statement. Three of our friends, it read, talented and experienced climbers
have lost their lives on the icy slopes of this mountain. This is an unspeakably painful,
irreparable loss for the entire family of Latvian mountain climbers.
The Park Service, following protocol, withheld the names for 72 hours. It was the LAS that chose
to name them publicly. Ineze Puceka Vija Olte and Renars Kuniksalaks, so their families and
their country would know who had been lost. By the morning of May 30, rescuers had reached the camp.
Purins, Medzoulis, and Svarins were brought off the mountain. In Talkeetna, the small Alaskan
town at the base of the flight path that carries climbers in and out of Kahiltna, three survivors
stepped off a helicopter into a world that suddenly felt very different. Martins Bilzins
remained in hospital. The latest reports indicated doctors were not concerned for his life.
When you lay the facts in sequence, a terrifying picture begins to form.
The first failure is the section itself. The autobahn had been accumulating a body count
since at least 1980. More than 14 deaths in 46 years on a stretch of mountain less than a mile
wide. The Park Service publishes specific warnings about it. The guide community knows it by name.
The risk is documented, posted, and communicated to every team that registers to climb.
And yet, it keeps happening. The second failure is altitude. At 18,000 feet,
the human brain is operating on approximately 60% of its normal oxygen supply. That does not
feel like confusion. It feels completely normal, which is exactly the problem. Reaction times slow.
Fine motor control degrades. The ability to self-arrest a fall, to drive an ice axe into a
slope in the first critical seconds before a slide becomes a free fall, is compromised in
ways the climber cannot perceive in the moment. The third failure is protection. The Park Service
specifically notes that most deaths on this section of the mountain result from unprotected
falls. Fixed pickets help. But they do not cover every meter. And the higher you go,
the sparser they become. And the fourth failure, the one that haunts every roped climbing team,
is what mountaineers call the cascade. When climbers are connected to each other,
which is standard practice on this terrain, a single person's fall can become four people's fall
before anyone has time to respond. Each of these factors alone is manageable. Together,
on the same slope, at 18,000 feet, in the dark, they formed what safety researchers call the
Swiss cheese model. Every layer of protection had a hole. On May 28th, those holes lined up perfectly.
The Latvian Mountaineering Association said it plainly. This is an unspeakably painful,
irreparable loss. There is nothing to argue with in that sentence.
Inisi Pučeka, Viđa Olte, and Renars Kunig Salaks died because every small, invisible failure
lined up perfectly for a tragedy none of them could have predicted.
