Bear 815 at Yellowstone National Park, also known as Obsidian Sow, has become something of a local celebrity after giving birth to three cubs last year. Unfortunately, the family's popularity has led some members of the public to endanger themselves in the hopes of getting a photo of the four at close range.
Last month, professional photographer Stacy ONell found herself stuck in a bear jam as Obsidian and her three yearlings crossed a road, and could only watch as over a dozen people piled out of their cars, cameras and phones in hand, for a closer look. She recorded the incident from inside her vehicle, and captured the moment Obsidian Sow changed direction and ran towards the assembled crowd to drive them away from her cubs.
