G is for Grizzly Bear
When you hike in Yellowstone it is smart to wear a bell or to sing while walking. That way if there is a grizzly bear around, he will know you are coming and won't be startled.
Did You Know?
There were no wolves in Yellowstone in 1994. The wolves that were reintroduced in 1995 and 1996 thrived and there are now over 300 of their descendents living in the Greater Yellowstone Area.
