A grizzly bear and a cub are seen along the Gibbon River in Yellowstone National Park, Wyo., in 2019. A hiker who was attacked by a bear — probably a grizzly — in Yellowstone National Park this week has been released from the hospital. The 29-year old man had been hiking alone on the remote Turbid Lake Trail when he apparently surprised the bear, according to park officials. Even seeing a grizzly bear is pretty uncommon in the lower 48 states. So the park, “will not be taking any management action against the bear.”Last year, Jon Kyle Mohr faced a similar encounter with a black bear in California’s Yosemite National Park.
