A pod of 107 pilot whales are seen stranded on Mason Bay on Stewart Island February 21, 2011. According to the Department of Conservation, two overseas visitors discovered the pod of 107 whales dead and dying at the southern end of the beach near Cavalier Creek. A decision by the department was made to euthanise the remaining whales, because high tide was 10 to 12 hours away.
