JACKSON, Wyo. — One of the best-known grizzly bears in Grand Teton National Park has emerged from her den with three new cubs.
This is the third year that Grizzly 399 has produced a litter of three cubs. She gave birth to a single cub one year.
Grizzly 399 and one of her offspring, Grizzly 610, are well-known in Grand Teton because of the amount of time they spend with their cubs along roadsides in the park.
The behavior makes the bears and their cubs unusually visible to tourists.
The bears often cause traffic jams as tourists stop to watch the animals. Biologists speculate that spending time near roads helps the bears protect themselves and their cubs from aggressive male bears.
