Cow elk are extremely protective of their young, as one unfortunate woman discovered while visiting Yellowstone National Park earlier this year. A video currently circulating on social media shows the woman approaching a cow, phone in hand, to take some close-up photos.
The National Park Service advises always staying at least 25 yards (23 meters) from elk, and the visitor soon discovers why as the animal charges and knocks her to the ground. Luckily she seems to be unharmed, and is able to walk away, lesson learned.
