The Elephant Back Loop Trailhead is temporarily closed to travel in Yellowstone National Park
The Elephant Back Loop Trailhead is temporarily closed to travel in Yellowstone National Park, Wyoming August 9, 2015. At least one grizzly bear attacked a hiker who was found dead and partially eaten in Yellowstone National Park in Wyoming, judging by wounds on his arms, park officials said on Saturday. A park ranger found the hiker's body on Friday in a popular back-country area near the Elephant Back Loop Trail near Yellowstone Lake in the middle of the park, park officials said.
