Those who haven't the patience to search out and observe the free-ranging wildlife of Yellowstone might want to check out this not-for-profit educational center. The interpretive center gives a detailed explanation of the history of wolves and grizzlies in this country, along with the difficult and controversial efforts to revive them in the wild. This is a closer look than you'll likely get at animals in the park, but did you really come to Yellowstone to look at grizzlies imported from Alaska in an enclosure?
