Ice breaks off glacier in New Zealand

Following an earthquake in Christchurch, New Zealand today, a 30-million ton chunk of ice broke off the mighty Tasman Glacier into the Tasman Lake. A number of tourists were on a pontoon boat on the lake just as the mountain of blue ice broke off the glacier. Anchor Lisa Mullins speaks with the skipper of that boat, Mark Bascand, who works for Glacier Explorers.
