(Undated) — A woman is critically injured after she was gored by a bison at Yellowstone National Park. The attack happened Monday near the Lake Lodge Cabins, on the North Shore of Lake Yellowstone. She was air-flighted to a hospital in Idaho. It’s not yet known how close the woman was when the bison charged. It is peak breeding season, and park officials have issued warnings to use caution and keep at least 25 yards away from wildlife.
