While flying between the Alaskan cities of Kotzebue and Nome, a Coast Guard helicopter crew spotted an SOS sign on top of a shack. Circling back over the remote mining camp, they found a man waving his hands in the air.
Friends had reported him missing after he hadn't returned to his Nome home. It turned out the man had been mauled by a bear days earlier, the crew realized when they finally got to him last week. That attack bruised his torso and injured his leg, according to the Coast Guard.
The man was taken to a Nome emergency room, the Coast Guard said in a statement Tuesday night.
"The man reported that the bear had returned to his camp and harassed him every night for a week straight," the Coast Guard said. The Coast Guard has not released details about his identity.
It's unclear what type of bear attacked the man, but both black and brown bears are common in the state. Alaska has an estimated 30,000 brown bears and 100,000 black bears, according to the Alaska Department of Fish and Game.
Ever wonder what you should do if when in bear country? This is what the Alaska wildlife agency recommends.
