A tourist inadvertently walked up to a bison at Yellowstone National Park, despite warnings from onlookers. The National Park Service instructs visitors to stay at least 25 yards away from animals such as bison, which can reach speeds of 30mph. The incident was captured on the touronsofnationalparks Instagram account. Despite the warnings, the visitor escaped without serious injury. Bison are responsible for more injuries at Yellowstone than any other animal and may be euthanized even if provoked. While Yellowstone will fine visitors who disturb wildlife, a third called for more accountability to prevent similar incidents.
