A 5-year-old bear whose mother was considered the world's most famous grizzly was found dead after being struck by a vehicle in Wyoming's Grand Teton National Park, authorities said.
Wildlife rangers discovered the bear, Grizzly 1058, on May 6 along a highway within the park east of the Buffalo Fork River, according to a statement. Investigators say he was hit by a car and made it to a willow about 125 yards from the road, where he died.
The bear was identified by wildlife tags and national forest officials said he likely died days before his body was discovered.
Grizzly 1058 was one of the well-known offspring of Grizzly 399, a mama bear that for more than two decades had been studied by scientists and celebrated by wildlife enthusiasts and photographers. Grizzly 399 died in October after it was struck by a vehicle in Snake River Canyon, just south of Jackson, Wyoming.
Her death set off a flood of tributes across the nation as park visitors, researchers and others recalled memories of the grizzly and hailed her as "the most prominent ambassador" for the grizzly bear species.
In February 2024, Grizzly 399 was featured in her own PBS documentary, "Grizzly 399: Queen of the Tetons," which followed her as she raises four new cubs, including Grizzly 1058.
After the death of his mother, Grizzly 1058 had occasionally been observed in the park, but no confirmed sightings of him this spring had been reported, according to the park.
