CHEYENNE, Wyo. — A famous grizzly bear beloved for decades by countless tourists, biologists and professional wildlife photographers in Grand Teton National Park is dead after being struck by a vehicle in western Wyoming.
Grizzly No. 399 died Tuesday night on a highway in Snake River Canyon south of Jackson, park officials said in a statement Wednesday, adding the driver was unhurt. A yearling cub was with the grizzly when she was struck and though not believed to have been hurt, its whereabouts were unknown, according to the statement.
The circumstances of the crash were unclear. Grand Teton and U.S. Fish and Wildlife Service officials said they had no further information to release about the crash.
At 28 years old, No. 399 was the oldest known reproducing female grizzly in the Yellowstone ecosystem. Each spring, wildlife enthusiasts eagerly awaited her emergence from her den to see how many cubs she had birthed over the winter — then quickly shared the news online.
Named for the identity tag affixed by researchers to her ear, the grizzly amazed watchers by continuing to reproduce into old age. Unlike many grizzly bears, she was often seen near roads in Grand Teton, drawing crowds and traffic jams.
Scientists speculate such behavior kept male grizzlies at a distance so they would not be a threat to her cubs. Some believe male grizzlies kill cubs to bring the mother into heat.
The bear had at least 18 cubs over the years, including a litter of four in 2020. She stood around 7 feet (2.1 meters) tall and weighed about 400 pounds (180 kilograms).
News of the bear's death spread quickly on a Facebook page that tracks the sow and other wildlife in Grand Teton and Yellowstone national parks. More than 1,000 people posted comments calling the grizzly a “magnificent queen,” an “icon” and an “incredible ambassador for her species.”
They were heartbroken and devastated by her death, calling it a tragic loss.
"She has inspired countless visitors into conservation stewardship around the world and will be missed,” Grand Teton National Park Superintendent Chip Jenkins said in the statement.
The grizzly lived through a time of strife over her species in the region, as state officials have sought to gain management control over grizzlies from the U.S. Fish and Wildlife Service, saying the bears' numbers have rebounded past the point of being at risk.
Conservation groups have objected, saying climate change imperils some of the bears' key food sources including whitebark pine cones.
Some 50,000 grizzlies once roamed the western United States. But outside Alaska they are now confined to pockets in the Yellowstone region and northern Rockies. They dwindled in the Yellowstone region to just over 100 animals by 1975, when they were first protected as a threatened species.
The region encompassing Grand Teton and Yellowstone national parks and surrounding areas in Wyoming, Montana and Idaho is now home to some 1,000 grizzlies. They remain federally protected but have bounced off and back on the threatened list twice in recent years.
Government biologists say the population is healthy and officials from the three Yellowstone states continue to seek their removal from federal protection.
On average, about three grizzlies annually in the region are killed in vehicle collisions, with 51 killed since 2009, according to data collected by researchers and released by the park. No. 399 was the second grizzly killed in the region by a vehicle this year.
“Wildlife vehicle collisions and conflict are unfortunate. We are thankful the driver is okay and understand the community is saddened to hear that grizzly bear 399 has died,” Wyoming Game and Fish Department Director Angi Bruce said in the statement.
