Debra reviews (for the last time) her plane journey to Antarctica. She defines a desert (of which Antarctica is the largest). A glimpse of the weather base at McMurdo Station gives weather reports that affect everybody on the ice. Debra flies to Taylor Valley, a dry area with little ice, to meet a geologist. MUSIC VIDEO: Arctic vs. Antarctic.
