Antarctica: The Desert Continent (7x5)

Air date: Oct 14, 1988

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.
