In the breathtaking but brutally unforgiving backcountry of Glacier National Park, where jagged peaks pierce the Montana sky and grizzlies rule the shadows, another hiker’s peaceful trek turned into a blood-soaked nightmare. Eyewitnesses froze in horror as a piercing scream ripped through the air near the pristine shores of Lake Josephine. “We heard a scream,” recounted 21-year-old Devin Dufrene, who was hiking with his sister and friends when chaos erupted on May 21, 2026. Moments later, a panicked man from the group ahead came sprinting back, desperately yelling “bear attack!”

This latest savage encounter marks the second bear-related horror in Glacier National Park in a matter of weeks, sending shockwaves through the outdoor community and forcing immediate trail closures once again. Just days after the trail reopened following bear activity warnings, a hiker was reportedly injured in a sudden, defensive assault by a grizzly or black bear on the scenic but treacherous path connecting Lake Josephine’s north shore to the iconic Grinnell Glacier Trail.

The Heart-Pounding Moment Terror Struck

Devin Dufrene and his small group were enjoying the stunning views along the windy trail – known for its blind corners and limited visibility – when the unimaginable unfolded around 1:30 p.m. “Shortly after, a person from the group in front of us was running back screaming, ‘bear attack,’” Dufrene told reporters. The group tried to calm the frantic runner, but he continued bolting past them in sheer panic.

Dufrene quickly used a satellite device to alert emergency services. But the nightmare was far from over. As they turned to retreat toward the trailhead, another bear appeared walking directly toward them on the path. With an attack already reported up the trail, the group made a split-second life-saving decision: they scrambled up a steep cliffside and waited in terrified silence for the massive animal to pass.

Their quick thinking paid off. Rangers responded with remarkable speed, arriving on scene by around 1:50 p.m. Dufrene witnessed them heading deeper into the trail carrying an empty stretcher – a chilling sign that the attacked hiker had been seriously injured and required evacuation. New closure signs went up immediately, shutting down trails past the Many Glacier Hotel.

Park spokesperson Autumn Sifuentes later confirmed a “surprise encounter involving a hiker and a bear” on the Grinnell Glacier Trail. The North Shore Josephine Lake Trail and connecting paths remain closed as officials investigate. No further details on the victim’s identity, exact injuries, or the bear’s species have been released, but the hiker is believed to have survived the mauling.

A Park Still Reeling from Recent Horror

This attack comes on the heels of a rare and devastating fatal bear encounter earlier in May 2026. On May 3, 33-year-old Anthony Pollio from Davie, Florida, set out on the Mount Brown Trail but never returned. His remains were discovered days later, about 50 feet off the path in a heavily wooded area, with injuries consistent with a grizzly bear attack. It was the first confirmed fatal bear mauling in Glacier National Park since 1998 – a shocking 28-year drought broken in the most brutal way.

Pollio, described by family as a “fearless,” educated, and experienced outdoorsman who loved adventure, became another tragic statistic in a wilderness that demands respect. His death sent ripples of fear through hikers nationwide, yet the park reopened sections of trail shortly after – only for this latest incident to erupt near the popular Many Glacier area.

Why Glacier Is Becoming a Bear Battleground

Glacier National Park, often called the “Crown of the Continent,” is home to an estimated 300 or more grizzly bears and hundreds of black bears. The area around Lake Josephine and Grinnell Glacier is prime habitat – lush with berries, fish, and dense cover that makes surprise encounters terrifyingly common if hikers aren’t vigilant.

The trail where the latest attack occurred had been closed as recently as May 21 due to bear activity before briefly reopening. Just days prior, two other hikers captured dramatic video of two young grizzlies charging past them on the South Shore Trail. In that close call, the hikers deployed bear spray and escaped unharmed, but one woman was heard shouting in the footage, “We’re going to die. We’re actually gonna die.”

Experts emphasize that most bear attacks are defensive – mothers protecting cubs or animals startled at close range over food sources. The windy trails with blind spots around Lake Josephine create perfect conditions for exactly these kinds of sudden, explosive encounters.

Survivors and Witnesses Speak Out

Dufrene, on his first visit to Glacier, remained remarkably composed in the aftermath. “All in all, nature will do as nature does,” he said, crediting his group’s preparedness, quick thinking, and the excellent response time of rangers. They made noise as instructed while retreating, a key safety practice in bear country.

His account paints a vivid picture of the raw terror: the initial scream echoing off the mountains, the sight of a grown man fleeing in panic, the second bear emerging like a ghost from the wilderness, and the desperate scramble up the rocks to safety.

For the unnamed victim of the May 21 attack, the ordeal likely involved claws, teeth, and sheer power. While details are scarce, the need for a stretcher evacuation suggests significant injuries requiring medical transport, possibly by boat across the lake or helicopter.

Rising Fears Spark Safety Reckoning

These back-to-back incidents have ignited intense debate about safety protocols in America’s wildest national parks. Should more trails stay closed longer during peak bear activity seasons? Are hikers receiving enough education on bear spray use, group hiking, and noise-making? And with climate change and habitat pressures pushing bears into more frequent human contact, is Glacier – and parks like Yellowstone – facing a new era of danger?

Park officials urge visitors to carry bear spray, hike in groups, make noise, and respect closures. Yet as summer tourism ramps up, the allure of Glacier’s turquoise lakes, towering glaciers, and pristine wilderness continues to draw thousands – many unaware of the lethal risks lurking in the underbrush.

A Stark Reminder: Nature Doesn’t Care

The hiker attacked near Lake Josephine joins a growing list of those who learned the hard way that Glacier National Park is not a theme park – it is raw, untamed wilderness where humans are visitors, not rulers. The scream that pierced the afternoon air on May 21 serves as a haunting warning: one wrong step, one blind corner, one moment of silence instead of noise, and paradise can become a battlefield.

As rangers continue their investigation and the injured hiker recovers (details on their condition remain private), the park’s famous trails sit empty once more under fresh closure signs. Families planning dream vacations are left second-guessing. Outdoor enthusiasts debate whether the risks now outweigh the rewards.

Devin Dufrene and his group made it out safely. The runner who first raised the alarm survived to tell the tale. But for one hiker on an ordinary afternoon trek, the bear’s sudden charge changed everything.

In the shadow of the Rockies, where grizzlies have roamed for millennia, Glacier National Park reminds us with blood and screams that some encounters end in survival stories – and others in tragedy. Hikers, heed the warnings. Carry the spray. Make the noise.

Because in bear country, the next scream you hear could be your own.
