The Legend of Black Thunder Mountain(1979)

Overview

Separated from a wagon train, Mr. Parish and the children are attaced by armed men, forcing young Anna and Jamie to flee into the wilderness with their father's fate unknown. They don't realize they carry a secret treasure map, but with gold-hunting George and Buzz in pursuit and wild-eyed mountain man McTavish on the loose, there's plenty to fear. Yet help comes from the unlikeliest of places, including a ferocious wolf pack, the majestic wild eagle, Balderdash, and even a maternal grizzly, which they name after their friend Mrs. Mullen.
