Authorities search for visitors who harassed bison calf at Grand Teton National Park.

Authorities are searching for two individuals who allegedly approached and harassed a bison calf at Grand Teton National Park in Wyoming. The National Park Service is reminding visitors to view wildlife safely and responsibly, maintaining a distance of at least 100 yards from bears and wolves, and 25 yards from other wildlife. Interference by people can cause wildlife to reject their offspring, and often these interactions result in euthanizing the animal. Anyone with information on the individuals involved should contact the park Tip Line 307-739-3367.
