Grizzly Bear 399 was killed on Tuesday in a car collision south of Jackson, Wyo., the National Park Service said. She was fatally hit by a vehicle on Highway 26/89 in Snake River Canyon and was later identified by her ear tags and microchip. The mama bear had a yearling cub with her at the time, but it’s still missing.

Car crashes with wildlife can be common across the species’ range, officials said. Nearly 50 grizzlies died in crashes from 2009 to 2023 in the Greater Yellowstone Ecosystem, and an average of 3.3 bears died from car crashes each year during that time period, officials said.

The bear known as Grizzly 399, who PBS dubbed the "most famous grizzly in the world," was killed Tuesday evening after being hit by a car in Wyoming, according to officials. The U.S. Fish and Wildlife Service said the bear was identified through her microchip after being hit on a highway in Snake River Canyon near Jackson,
