P is for Pronghorn
Pronghorn are the fastest runners in Yellowstone. When they need to, they can run at 70 miles per hour (113 kph) for three to four minutes. That's as fast as most cars go on the highway.
Did You Know?
Even though the animals of Yellowstone seem tame they are still wild. Feeding the animals is not permitted in any way, and all visitors must keep 100 yards away from wolves and bears, and 25 yards from other animals.
