Grand Teton officials: 'No reason to believe' 399 won't emerge from den

“I felt she was quite healthy,” he said. “If she did actually go to den, she’ll probably have two or three cubs.”

Schwabedissen also said the last confirmed sighting of 399 was in mid-September of last year. He said there were more reported sightings afterwards that were “likely to be her.”

Without a GPS collar, 399’s exact whereabouts are unknown.

“However, we fully expect that she is denned up,” Schwabedissen said.

While 399 is “at the upper end of a grizzly bear’s lifespan,” her body condition “did look good” last fall, he said.
