On November 6, 1994, twin polar bear cubs Klondike and Snow were born to a first-time mother named Ulu, who rejected the cubs. They were successfully raised by zoo staff and became a popular attraction. The bears were transferred to SeaWorld Orlando. In 2012 Snow was transferred from Sea World in Orlando, Florida to the Reid Park Zoo in Tucson, Arizona, where she died unexpectedly on September 2, 2012. Klondike died at SeaWorld Orlando on September 13, 2013. Their story is commemorated at the Denver Zoo by a bronze sculpture located across from the main polar bear viewing area.
