According to the Huffington Post, last year a man in a realistic-looking bear costume, complete with head, ran through the area close to a weir on the Chilkoot River near Haines. A crowd had gathered near the weir to watch a sow and two cubs who were feeding there. They were startled when the man, dressed as a bear, began to jump up and down and then got within 5 to 10 feet of the cubs. An Alaska Fish & Game technician moved the sow away for the man’s safety, and then tried to talk to the man, who refused to identify himself. The man then drove off, never removing his costume. The article said troopers were investigating and the man could face wildlife harassment charges.
Why was he bothering the bears in the first place? No one knows. Perhaps he felt they were getting more than their share of salmon.
