Yellowstone visitors under investigation for putting elk calf in car.
Yellowstone National Park officials are investigating after visitors reportedly put an elk calf in their car over Memorial Day weekend. The young elk was later brought to the West Yellowstone Police Department in Montana and ran into a nearby forest. This incident follows a recent encounter where a Hawaii man interacted with a bison calf that rangers were later forced to kill. Yellowstone is warning visitors to protect the park's wildlife and to follow park regulations, which require visitors to remain at least 25 yards from all wildlife and at least 100 yards from bears and wolves.
