Thought this was interesting. edit - Says four of them took photos, wish they had put a couple with this article.

Karen Noyce set the frequency on her radio-telemetry receiver and pointed its antenna into the pines of Chippewa National Forest near Marcell last week. Noyce heard high-pitched intermittent chirps.
"That's her," said Noyce, a wildlife research biologist with the Minnesota DNR in Grand Rapids.
South of us, the oldest known wild bear in the world -- 39 years old -- was resting peacefully in her den,
Noyce began walking south, along with Dave Garshelis, the DNR's bear project leader.
"No known bears of any species have lived longer in the wild, based on age estimates from teeth taken from harvested bears," Garshelis said. "(That includes) more than 60,000 specimens just in Minnesota and at least a million overall."
Several hundred yards from the road, we could see the den.
And, there, under an upturned stump with roots dangling from a 15-by-15-inch opening, was the bear that biologists call No. 56. She stirred slowly. In hibernation, Garshelis said, bears remain drowsy, body temperature falls from 99 to about 90 degrees, their heart beats more slowly, becoming intermittent.
"She's missing part of her right ear tag," Garshelis whispered.
Four of us recorded video of No. 56 and took photographs for perhaps half an hour.
Wildlife biologists know that she is 39 years old because they counted seven rings in a tooth they extracted from her in 1981, when she was first captured and radio-collared. That reliable aging technique indicated the bear had
been born in 1974. Researchers track her now because her longevity is so remarkable.
Since 1981, the DNR has radio-collared and tracked more than 550 black bears. The next oldest bears in those studies included two that reached age 23. One is a granddaughter of No. 56.
"Half the females in Minnesota don't live past age 4," Garshelis said. How does No. 56 do it?
"She has stayed away from houses and hunters' baits," Garshelis said, "We've (lately) made a concerted effort to ask people not to shoot her, even if she does come to a bait."
Over the years, she produced 11 litters and 28 or 29 cubs. She first gave birth at age 5 and last produced a cub at age 25, Garshelis said.
Only 14 of more than 350 radio-collared bears tracked by the DNR have died naturally. "We're hoping she doesn't die due to a human cause," Garshelis said.
Noyce plans to place cameras near the den. In late March, the videos may show the oldest known bear in the wild, emerging into another Minnesota spring.
