Climbers on scaling Antarctica mountains, spirit of exploration
Hidden deep within Antarctica's icy terrain lie half-a-dozen mountains that few climbers have summited. One group decided to scale all six, something no one had ever done before. They completed the expedition in less than 10 days. Conrad Anker, Cedar Wright and Alex Honnold, three of the all-star North Face climbers who recently returned from that journey, join "CBS This Morning" to discuss their experiences.
