Expedition Wild

Casey Anderson and his best friend, an 800-pound brown bear, explore the realm of the Yellowstone grizzlies.

Casey Anderson knows about wild life. After graduating college he became an animal keeper at wildlife parks and orphanages around the world. Casey rescued a grizzly cub named Brutus from being euthanized and Brutus has been with Casey ever since.

Naturalist Casey Anderson treks deep into Yellowstone's back-country to explore how the park's diverse wildlife prepares for winter.

Casey Anderson creates a place for orphaned bears to live out a healthy and stimulating life with the construction of the Montana Grizzly Encounter.
