In the fall of 2013, Finnish climber Nalle Hukkataival took a trip out to Lappnor, Finland,听a new bouldering area about an hour east of Helsinki on the country's forested southern coastline. When he arrived, his old friend, Marko Siivinen, pointed out a nameless hunk of rock听the size of a bus that looked like it was about to topple over.
With just a few obvious holds on the flat face, Hukkataival, 30, could see the line to the top immediately. It looked like a V14 problem鈥攅xpert-level but not impossible. He stepped up to the wall and gripped two vertical ridges, compressing them as though he was closing a sliding door. But the moment he dabbed his right foot onto the wall, he plopped onto the padded mat beneath. It was the first sign that this project wasn鈥檛 going to be as easy as he鈥檇 thought. 鈥淚f it looked as hard as it is, I wouldn鈥檛 have even tried,鈥 Hukkataival says.
Hukkataival听gives Burden of Dreams a V17 grade. The number of climbers who have scaled a V15 is听fewer than 100. A V16? Just five.
Over the next four years, Hukkataival would make an estimated 4,000 attempts on the听bouldering project before finally conquering it last October. 鈥淚 thought he was going crazy at some point,鈥 Siivinen, 36,听says. 鈥淚 was feeling guilty that I showed it to him.鈥
Hukkataival has given it a V17 grade, which鈥攊f given the nod by future climbers鈥攚ould make it the hardest bouldering problem in the world. As a self-professed guardian of the integrity of the grading system, it鈥檚 not a claim he makes lightly, and top climbers who have visited the boulder agree it has potential. 鈥淚鈥檝e been traveling for 12 years non-stop,鈥 Hukkataival told 国产吃瓜黑料. 鈥淭he whole time I鈥檝e been looking for something with the perfect level of difficulty.鈥 (So far, no other top climber has repeated the ascent, which is the next step in corroborating the V17 rating.)听
To put things in perspective, a V0 bouldering problem is like climbing a ladder. Problems in the V4 to V5 range have skimpier handholds and require the technique and finger strength of a dedicated amateur. V9 and above are pro-level, the kind of problems featured in climbing competitions. Currently, the number of climbers in the world who have scaled a V15 is . A V16? Just five.
This boulder鈥攚hich Hukkataival christened Burden of Dreams after a 1982 documentary about director Werner Herzog鈥檚 monomaniacal quest to move a steamship over a mountain in the Amazon鈥攕tands alone. It is like Yosemite鈥檚 Dawn Wall writ small, an exercise in frustration that Hukkataival documents in a short film called the , which will be out February 8. The problem consists of just five or six hand movements to the top with funky moves like a piano match, where Hukkataival has to lift his index finger from a crimp to fit his other hand on securely. The footwork may be even more critical. In the beginning, Hukkataival couldn鈥檛 even do some of the individual moves, let alone string them together. In total, the climb is a combination of precise, dynamic lunges to sloping holds and powerful body-tensioning static moves.听
Hukkataival is the best climber you鈥檝e never heard of. He鈥檚 earned the respect of the sport鈥檚 elite, but he鈥檚 not a household name like Alex Honnold or Sasha DiGiulian. Part of the reason for his relative anonymity is that he abandoned the competition circuit early and works almost exclusively on smaller canvases: boulders not cliff faces. “It鈥檚 the purest form of a pushing yourself where you're not tied down by all this equipment,”听he says.听

He grew up in Helsinki but always loved spending time at his family鈥檚 cottage听in the Finnish听Archipelago. At 12, he started climbing in the gym, where the routes quickly grew too easy for him. Skipping holds felt contrived. He gave up climbing for more than a year until a friend took him to an outdoor crag. It was a revelation. 鈥淵ou just go from the bottom of the rock to the top,鈥 he says. 鈥淣o one tells you what you can do or not.鈥 In 2006, at the age of 20, he was invited to the Arco Rockmaster Competition. He won it and nabbed his first sponsorship from La Sportiva.
But instead of sticking with comps, Hukkataival bought a VW van and spent the next five years in it, exploring crags around Europe, then farther from home. During that time, he conquered some of the world鈥檚 most legendary boulders, including Dreamtime in Switzerland, once the gold standard V15, and Livin鈥 Large, a highball boulder in South Africa, where a 26-foot fall from the top would likely be fatal.
While scoring ascents on some of the world鈥檚 hardest routes, Hukkataival developed a deep skepticism of the scoring system. In March 2010, he wrote a 听about the exaggeration鈥攁nd subsequent demotion鈥攐f bouldering grades for new problems. 鈥淲e can all be throwing out big grades and flashy numbers and get on magazine covers, get better sponsorship and then a few months later watch our problem getting downgraded,鈥 he wrote.听
It seemed like every time someone made a first ascent of a challenging boulder problem, they would claim it deserved a V15 grade, a milestone that was first crossed in 2000 (or 2002, ) and听by 2010听hadn鈥檛 been surpassed. But as more people climbed a problem, the grade would slump to a V14. Hukkataival argued for a more conservative, wait-and-see approach to the grading system. 鈥淚 totally agree that we need to move up on the scale soon, but I'm not sure if the necessary (big) step has been reached yet,鈥 he wrote.
In 2011, when climbers first started throwing out V16 grades, Hukkataival maintained his miserly outlook. After he made the third ascent of Gioia, a possible V16 in Italy, whether it really deserved that grade.听
So how to justify his V17?

Calling it a V16 would have been a cop-out, Hukkataival says, a calculated move to avoid criticism or the sting of the next successful climber downgrading his problem. He wanted to push the grading system forward, and Burden of Dreams felt like the right boulder with which to do that. It鈥檚 unquestionably harder than anything he had ever successfully climbed before. He estimates he went to Lappnor more than one听hundred times, filming his attempts sometimes with the help of a cameraman, sometimes on his own.听
By the fall of 2015, Hukkataival felt like he had reached a pinnacle of readiness, and was moments away from sending the problem. Then the snow came. 鈥淚 stuck around for three weeks looking out the window,鈥 he says. Come spring, he started anew. Fumbling. Struggling. Falling.听
As spring turned to summer, his sweaty fingertips foiled the friction he needed to cling to the wall鈥檚 slight bulges. Top climbers, including Daniel Woods and Jimmy Webb, made pilgrimages to Lappnor and agreed that it lay on that thin line that divides the possible from the impossible. 鈥淲eeks and months turned into years of uncertainty and self-doubt,鈥 Hukkataival later wrote on Instagram. 鈥淭rying to keep that little spark of hope in the back of your mind alive.鈥
On October 23rd, Hukkataival was out there all alone. He set up his camera and stepped up to the boulder. Everything came together in that one moment. That perfect sequence of moves. Four years flashed before his eyes. He mantled over the lip and couldn鈥檛 believe it. When he got down, he texted his friends in Finnish: 鈥淪e meni.鈥 It went.听
It was over.听Whether or not the V17 grade sticks,听Hukkataival is already onto his next punishing mega-project. Over the winter, he spent some time in Yosemite with eyes not on the big walls, but on a wet, moss-covered boulder in the valley.
