Outdoor Life – Japanese photographer Shogo Asao, 60, came across these two brawling bears while exploring Alaska’s Katmai National Park.
At first the bears just watched one another and roared challenges, Asao told the Daily Mail. Then they stood up on their hind legs, clawing and swiping each other’s snouts. At one point, one of the grizzlies broke away and fled toward Asao until it was just 10 feet away. The second bear charged after it for a fresh attack.
