MOOSE—Julia Nell was driving with Tom Mangelsen last week when news broke that tragedy had befallen Grizzly 399 in the Snake River Canyon. 

She asked him to pull over. A wildlife photographer who’d been documenting the storied grizzly bear for decades, Mangelsen knew what happened before she said it. Grizzly 399 was dead.   

That night, Nell heard the depth of Mangelsen’s grief. His crying was “animalistic.” 

“I’ve never heard anyone cry or wail the way that he did,” said Nell, whose own voice quivered. “It went on for a long time.” 

Nell recounted the memory to a few dozen mutual friends who’d gathered at Mangelsen’s house on Saturday to celebrate the record-breaking grizzly sow’s life. She articulated why the 28-year-old grizzly bear meant so much to the 78-year-old photographer, both longtime residents of Jackson Hole. 

“Tom spent 150 days of the year [for 18 years] following this bear,” Nell said. “I think it’s the longest relationship he’s ever had with a woman.”

Everyone laughed. But given the gathering’s purpose, there were good odds that they, too, felt great pangs of sadness when they learned of the vehicle accident that killed the grizzly bear made famous by her choice of habitat: the side of the road in Grand Teton National Park.    

In the aftermath of 399’s death, heartfelt remembrances of a grizzly bear flooded social media feeds from around the globe. Online and face-to-face, Grizzly 399’s avid fans and occasional observers paid homage to an intelligent ambassador of her species who was able to deftly navigate many millions of crowded, gawking tourists while raising 18 cubs along the way. By one account, businesses in Jackson Hole temporarily ground to a halt as employees processed the news. People grieved privately, and in public. 

‘Forever grateful’

Tyler Brasington, a bear management ranger for Grand Teton National Park, bid 399 farewell in a note his employer propagated that concluded he was “forever grateful” for the chance to have worked alongside the grizzly bear. 

“I often explain to people it’s not only about who she is — it’s about what she’s taught us about her species, and about ourselves,” Brasington wrote. “Grizzly 399 embodied resilience, adaptability, and tolerance throughout her life. She taught me the importance of resilience — how to bounce back quickly in times of hardship or struggle.”

Word of Grizzly 399’s death quickly went viral, crossing oceans. Headlines exploded in the Guardian, New York Times, Washington Post, National Geographic, USA Today and in the bruin’s hometown paper, the Jackson Hole Daily

Wildlife activist and Jackson resident Ann Smith was in California when she received word of 399’s demise. After following the grizzly sow for two straight decades — she likened the bear-watching outings to a “treasure hunt” — she was immediately devastated and remained so nearly a week later. 

“It’s probably the hardest thing I’ve ever had to deal with in my life, and I’m 83 years old,” Smith told WyoFile on Monday. “She was almost like a part of my family. Someone told me, ‘It’s because you didn’t have grandchildren.’ I said, ‘That could be.’”

Smith’s daily correspondence with friends let her know she’s not alone in taking the loss of a grizzly bear with difficulty. 

“I’m still getting messages from friends who’ve said, ‘I just can’t stop thinking about her, I can’t stop crying,’” Smith said. One Jackson friend messaged her to say that her “entire office stopped working” and that “nobody could do anything.” 

Paralyzing grief

For avid grizzly watchers and photographers, Grizzly 399’s death hit especially hard because of the frequency, proximity and volume of encounters — many had shared 399’s presence hundreds and hundreds of times. They felt they knew her, even sharing a kinship that transcended species. Mangelsen believed that the grizzly bear was often drawn to where he was parked amidst the sometimes unmitigated chaos of a roadside “bear jam.”

“I think she recognized my smell,” he said. “She would cross in front of my car more often than others. I think she felt safe when she smelled our vehicles. That may be just speculation.” 

The more general public, especially in Jackson, also reacted with emotion to an individual animal dying in what authorities have described as a faultless accident. That’s partly explained by the many twists and turns of the matriarch grizzly’s life, which has been routinely documented in news and over social media — she’s even the subject of several books.

Thought to have been born in the middle of the Clinton administration in 1996, Grizzly 399 spent her first decade of life as just one more anonymous bruin. In 2006, however, she took to raising her second litter of cubs in view of the road system in the northern portion of Teton Park. Included in that litter was Grizzly 610 — 399’s now 18-year-old daughter, another road-tolerant sow who almost lost her own life in a vehicle collision in fall 2023.  

Grizzly 399 repeated the cub-rearing pattern every third spring over the next 18 years. Without failure, she reproduced and reemerged with a new litter.

Yet, her life wasn’t always smooth. 

A tough, but successful life

In 2007, with three yearlings at her side, the grizzly mauled a Lander man whose morning jog from Jackson Lake Lodge fatefully brought him by a freshly killed elk carcass. The Jackson Hole News&Guide’s report about the incident dubbed the then 11-year-old grizzly bear a “minor celebrity.” Times changed, and Grizzly 399’s celebrity status grew dramatically as she aged. Smith joked that she “should have written Harrison [Ford]” just to let the movie star know he was no longer Jackson Hole’s best-known resident.

Grizzly 399’s cubs were hit and killed on park roads, in 2012 and again in 2016. Near the tail end of her life, the civilization-tolerant sow took to periodically leaving Teton Park and cub-rearing — sometimes for weeks at a time — in the southern, developed portion of Jackson Hole. 

During those outings, her diet took a concerning turn as she took advantage of human-related food on the landscape, like livestock feed and an apiarist’s colony. Grizzly 399 was purposefully fed, too — there was an investigation, but no prosecution — yet the often-true adage “a fed bear is a dead bear” didn’t ring true for Grizzly 399. 

That’s largely because state and federal wildlife managers gave her special treatment in recognition of her global fame. The U.S. Fish and Wildlife Service’s grizzly recovery coordinator, Hilary Cooley, even dispatched a special unit to keep watch over and avert conflicts with the beloved, embattled bruin during at least one extended foray into the more developed corners of Teton County. Those same protections were not extended to her cubs, who ran into trouble and were killed after dispersing from their famous mother. 

Grizzly 399 broke up the harder times with feats that inspired awe. The day Grand Teton National Park reopened after an extended COVID-19 closure in 2020, she emerged from the den at age 24 with four cubs — an exceptional rarity (2% of litters).

Three years later, at 27, she came out with a single cub. Remarkably, that made her the oldest monitored grizzly in the history of the Greater Yellowstone Ecosystem to bear a litter — a literal record-setter.  

All the while, the grizzly’s faithful fan club documented her every move, tracking and photographing the bear from the day she emerged until she trekked for the den. The longevity and successful cub rearing on a landscape thick with tourists, bear-watchers and hazards in every direction was not dumb luck. 

Interagency Grizzly Bear Study Team leader Frank van Manen credited 399 for her smarts.

“One of my employees who captured her during several research captures described her as ‘intelligent, graceful and patient,’” van Manen told WyoFile. “That captured her characteristics pretty well. That’s the reason why she was able to stay out of trouble most of the time.” 

Sent off 

At the weekend gathering at Mangelsen’s house, friends and fellow grizzly photographers and enthusiasts shared grizzly-watching memories. Charlie Craighead lamented how his pioneering grizzly biologist father, Frank Craighead, never got to experience Ursus arctos horribilis’ return to Jackson Hole, let alone study a bear like Grizzly 399.

“They were in Yellowstone, they were in the Teton wilderness — but not down here,” Craighead said. “And now we’ve had them in the yard at dad’s house up at Moose.”

Jackson Hole resident Sue Cedarholm reflected on the endless hours wildlife photographers like herself spent waiting on the side of the road, bonded together by Grizzly 399.

“We’re so lucky we had all the time we had with her,” said Cedarholm, who wore a 399 t-shirt. “Some of my dearest friends are people who I met on the side of the road. Actually my partner, who I now live with, I met on the side of the road. It’s been an amazing experience.” 

In life and death, Grizzly 399 catalyzed activism.

In 2018, when the Wyoming Game and Fish Department was making preparations for its first grizzly hunting season since the 1970s, the esteemed sow’s existence prompted the state to propose a no-hunting buffer lining the east boundary of Grand Teton National Park. Not satisfied, passionate pro-grizzly activists launched the “Shoot ‘em with a camera” campaign, encouraging non-hunters to apply for the few available tags. Against very long odds, Mangelsen drew one of the licenses to partake in the hunt — which never happened due to a federal judge’s decision.  

Attendees at the Saturday gathering pushed to keep on fighting for the cause of conservation to honor Grizzly 399. Wyoming regulations that enable a culture of running over wildlife with snowmobiles were brought up more than once. Advocacy for the grizzly bear herself is also still alive. 

“We cannot, under any circumstances, let her be taxidermied,” Cedarholm told the group.

Instead, she said, a fitting tribute would be to cremate 399 and spread her ashes where she mostly resided, Teton Park.

The Fish and Wildlife Service is still determining what to do with the remains, according to spokesman Joe Szuszwalak. 

A candlelight vigil has been organized in honor of Grizzly 399 on the Jackson Town Square. It’s open to the public and begins at 6 p.m. on Saturday.

  1. The driver driving that night knew the highway is treacherous and knew wildlife crosses the road and did not reduce his speed from 55mph to a lower speed which caused an unsafe driving condition as a result struck and killed beloved 399 and can only hope Spirit is still here with us. The agency has failed Grizzly 399 by not going out to the area where a man called explaining I think 399 and her yearling could be eating on a carcass; not one agent had gone out to check and remove the carcass.
    I believe at least 65 grizzlies lost there lives to humans and not one citation has been issued on a protected animal under the “Endangered Species Act” it appears that the agents are not performing there job duties and failing these animals to be protected and allowing them to die with no accountability.
    I am grieving over the loss of beloved Grizzly 399 as she showed us so much love for her cubs and showing us a part of her world that we will never get back and we have to speak on behalf of these animals and advocate for them as we have to be there voice.
    Thank you Tom for all the years for her photos with her beautiful cubs and her story of her life and thank you for the documentary it truly touched my life more than you will ever know.
    Thank you Grizzly 399 for showing us a part of your world and being a loving mother to all your cubs. RIP Beautiful Grizzly 399 you were a Beautiful and Classy Lady.

  2. Deeply sorry for the loss of your beautiful 399. I hope the years of photography of her story and her life will teach others around the country about this precious animal.🙏🏻❤️

  3. Nothing I’ve read or seen comes close to describing the grief caused by the loss of 399 like the first few paragraphs of this story. Thanks, Mike, for the touching reporting and thanks Tom, well, for everything.

  4. Great article about a wonderful animal. I do believe it is important that the speed limit be reduced at dusk. Many years ago my husband and I were going though Hayden Valley around dusk and a huge horned owl flew directly across the windshield of the car. I can still see this image in my mind after 40 years. We all need to do better carrying for all the animals that cross our paths.

  5. I grew up around Yellowstone Park and loved the bears. Now I live in Arizona and don’t see too many bears, but Grizzly 399 always gave me the “fix” I needed. I loved watching her and her cubs. Thanks everyone for the great photos. I will miss her so much.

  6. It was with sadness I read of the beautiful bears passing. Scattering her ashes in her favourite places would do her honour🇨🇦🇺🇸

  7. Now my concern lays with her cub who was no doubt dramatically traumatized by the incident and subsequent parting from his mom…he or she may be big enough to survive but will they adjust? It is so very concerning…I’d appreciate any comments from knowledgeable people on this…

  8. I’m wondering whether 399’s tragic death could further safe wildlife crossings on our nation’s highways. Donations to a special fund for “399 Safe Crossings” or to the Center for Large Landscape Conservation (https://largelandscapes.org/) could save the lives of many other bears, elk, deer, moose AND motorists. Perhaps one such crossing near 399’s favorite roadsides could be named in her honor. A bronze, life-size statue of 399 and her cubs could highlight a roadside pullout where interpretive signage could explain her significance to the Greater Yellowstone Ecosystem and her tragic death.

  9. Mike, thank you for a wonderful story. I did cry as I read about the amazing life of this beautiful animal. Thank you again for outstanding journalism.

  10. If you read the report by Lincoln Sheriffs deputy, you will realize that this WAS NOT a faultless incident. First, it was reported the driver was going about 55 mph which is the speed limit. However, the deputy stated it was an Ok speed in daylight, but speed should be reduced as much as 15 miles on this road in the dark. This driver DID NOT do that. He could have been going even a little faster. Then, they estimated the damage to his car at about $1,000 with the front end completely gone, the care not drivable and having to be towed. The driver said 399 just stepped out in front of the car and he had no time to brake. Seriously? NOT 399 behavior and “had no time to brake” seems to indicate excessive speed or paying no attention on the part of the driver. I suspect if the car would have been driveable the driver would have driven off. That happens a lot. Many of us believe that this was totally AVOIDABLE!

  11. There needs to be severe punishments for people that are not abidding by the speed limits in and around all of the state and national parks.

  12. I hope no wildlife are killed or injured by people driving to or from the 399 memorial. Driving anywhere in the Greater Yellowstone should be limited to what is absolutely necessary. This is true for everywhere else. For many years I have limited my driving in this way and have probably saved the lives of numerous swallows and horned larks and rabbits (and of the large animals, which I have never hit). If you love wildlife, stay home! Environmental groups should have their gatherings and fund-raising on-line.

  13. Perhaps the speed limit should be lowered at night in a area where animals are known to be. 55 mph seems a little high for a area like that where you could drive right up on something and not see it. A 45 mph speed limit at night might have saved 399.

  14. The bible verse in the book of Roman’s was fulfilled in this story: “They worship the creature instead of the creator”…

    1. Isn’t the animals an extension of the creator good or bad? Isn’t there something that says the creator lives in all these animals?

  15. I am a total bear lover and I so loved and respected 399. She was a great mother and a lady. Human mothers should take lessons of nurturing and loving offspring from our dear 399. She was always such a great mother.

  16. Please cremate #399 and spread her ashes in the park. A nice bronze statue or a grizzly totem pole in her honor would be a lovely way to honor her. Please don’t stuff her and put her on display!!

  17. A wildlife crossing at the site of 399’s death would do justice, I’m sure that donations would come in from all over the world to build it.

      1. Yes, a desecration of a wildlife corridor. It was built there to make money off tourists driving to see wildlife.

        1. I agree and I doubt 399 would have ever used it. She was comfortable crossing the road and her territory was vast. How would you even propose a location? Money better spent elsewhere like conservation, lobbying for slower speed limits and enforcement!

    1. You’re half correct Ray, it’s located at the national military vehicle museum in Dubois Wyoming
