Hypothermia and grizzly bears appear to be involved in the death of a hiker on the Bridger-Teton National Forest south of Yellowstone National Park, although investigators are still piecing together clues.
David Anderson, 24, was found lying face down in a marshy area of Bailey Meadows, off the Arizona Creek Trail on Wednesday. Officials estimate that he died Monday night.
"We're still speculating whether or not it was a hypothermia death and a bear contact after death, or did the bear contact come first and was hypothermia even involved," Teton County Sheriff Bob Zimmer said Thursday. "He had puncture marks and appeared to have been mauled by a bear."
Zimmer said there was not a significant amount of blood at the scene, indicating perhaps the bear came upon Anderson after death.
