A visitor from Southern California was gored by a bison in a park campground yesterday morning. The 55-year-old man from Norco, California, was staying in Bridge Bay Campground. About 11:30 a.m., he was taking pictures of a bull bison that was wandering among the campsites. When the two got to within about ten feet of each other, the bison charged the camper. The man received a puncture wound to the upper left thigh. He was treated at the Lake Clinic, then transported by ambulance to St. Johnâs Medical Center in Jackson, Wyoming. His injuries are not considered to be life threatening. This is the second time a park visitor has been injured by a bison this summer. A 50-year-old woman from Spain was tossed in the air by a bull bison in the Canyon area on June 24th while talking on a pay phone. She was treated for minor injuries. A bull bison can stand six feet tall, weigh up to 2,000 pounds, and run at speeds up to 30 miles an hour. Bison can be dangerous at any time, but may be more so during the next several weeks, which mark the peak of their mating season. Park regulations require people to stay at least 25 yards away from most animals, such as bison and elk, and at least 100 yards away from bears and wolves at all times. Those who fail to abide by these requirements not only put themselves in danger, they may also be subject to a citation and fine. Visitors desiring a closer look at animals are encouraged to use binoculars, a spotting scope, or the zoom lens on their still or video camera.
