Grizzly Bear 1058 Killed by Car in Grand Teton National Park
Using ear tags and a PIT tag, wildlife rangers identified the bear as 1058. Grizzly bear 1058 was a 5-year-old male bear when he was killed.
The bear appeared to be in good condition for his age and the time of year. The bear’s remains were put back onto the landscape in Grand Teton National Park.
GB1058 was one of four offspring that emerged with legendary grizzly 399 in May 2020. Grizzly 399 herself was killed by a car in the fall of 2024 just south of Grand Teton National Park.
Grizzly 1058 had occasionally been observed in the park since he was weened in 2022, but no confirmed sightings of him this spring had been reported.
Bears, elk, deer, moose, foxes and other wildlife are often near park roadways, difficult to see, and can cross the road unexpectedly. Drivers are reminded to:
- Obey the posted speed limit and maintain a safe following distance from other vehicles.
- Use caution and slow down, especially at dawn, dusk and at night when visibility is reduced.
- Follow the nighttime speed limit of 45 miles per hour on U.S. Highway 26/89/191. The reduced speed limit gives drivers and wildlife more time to react.
- Pay attention to your surroundings. Speeding is not the only cause of wildlife collisions; park wildlife are often hit because drivers are distracted.Call Teton Interagency Dispatch Center at 307-739-3301 to report wildlife-vehicle collisions, or harassment of wildlife in the park.
