He describes it like a kind of siege, carried out by two full-sized, aggressive grizzlies who seemed unfazed by barking dogs, a honking horn or the sound of a rifle. They "surrounded" his home and didn't relent until they were shot dead.
Cowan has seen bears on his rural property before — his dog chased away a black bear just last week. But it was clear almost as soon as he first saw the two grizzlies on Monday that something was off.
His teenaged daughter was in another cabin beside the house, and her dog was cowering outside the cabin door. Cowan then yelled out his window for her to let the dog in. When she opened her door, the bears "bolted" at her, too.
