The polar bear was more than 1 km away and began running toward the dog sled, quickly closing the distance on the frozen Arctic waters of Canada's Resolute Bay.
One of Mark Beeler's Inuit guides released two dogs to distract it while Beeler, a skilled bow hunter, quickly shot three arrows, piercing the animal's heart and lungs.
"You're thinking, I can't believe I paid this much money to be this close to a dangerous bear," said Beeler, who was less than 14 meters from the nearly 3½-meter-tall adult male when it came down.
