WILDLIFE WATCHING -- Grand Teton National Park’s most famous grizzly bear — dubbed 399 by researchers — is once again roaming the roadsides around Jackson Lake in Grand Teton National Park, and again with three new cubs at her heels.

The Jackson Hole News reports that starting in 2006, grizzly 399 raised three cubs within sight of roads in the Oxbow Bend, Willow Flats and Jackson Lake Lodge area of the park, delighting visitors and providing numerous opportunities for photographers. Researchers say 399 is about 15 years old.

The 399 sightings last weekend come after one of those 2006 cubs, 399’s 5-year-old daughter 610, was spotted last week with two cubs of her own. She was just a few miles away from her mother near Signal Mountain and the Potholes area.

“It’s incredible,” said photographer Tom Mangelsen, who operates Mangelsen-Images of Nature Gallery in Jackson. “Especially with three cubs again. She must be really fertile and healthy. It was a nice surprise.”

That 399 and 610 are raising their cubs so close to each other is exciting but not surprising, Grand Teton National Park senior wildlife biologist Steve Cain said.

“We know during years when neither of them had cubs, their home ranges overlapped significantly,” Cain said.
