Three Californian gray whales got caught in ice off Alaska in October 1988. Indigenous people, environmentalists, oil companies and even the Soviet Navy joined forces to try to free them. Rich Preston has been hearing from Cindy Lowri who was working for Greenpeace and who joined the battle to save the whales.Photo: Local indigenous children watch a gray whale nosing up through the ice.
