Cheyenne Mountain Zoo Celebrates the Long Life of Rosie, Andean Bear November 27, 2017 Cheyenne Mountain Zoo is sad to announce the passing of Rosie, our 28-year-old Andean bear. During her seven years here at Cheyenne Mountain Zoo, she made strong emotional connections with guests and staff alike. There are currently only four other Andean bears in North America that have survived to that age. Andean bears are also known as spectacled bears.
