World famous grizzly bear fatally struck in Wyoming had yearling cub with her

A beloved grizzly bear known as an ambassador for her species was fatally struck on a highway in Wyoming, National Park Service officials said Wednesday. 

Grizzly bear 399, who got her name through a research number assignment in 2001, had a yearling cub with her when she was hit on a highway in Snake River Canyon south of Jackson, authorities said. The cub's whereabouts are unknown, but there's no evidence to suggest that it was injured. 

The driver is OK, officials said. While the circumstances of the fatal crash were not immediately clear, authorities said 49 grizzly bears died because of vehicle collisions between 2009 and 2023.
