Path to top of Mount Everest open again

For 19 days, the route up to the summit of Mount Everest was obstructed by a huge block of ice which held back climbers from fulfilling their dreams of getting to the top of the world's tallest mountain. Sherpas were brought in to clear the ice and, earlier this week, it slowly disintegrated, opening the way. Hosts Marco Werman and Carolyn Beeler have the details.
