Miers Valley - Antarctica

Original description: "Located at 78 degrees South and 164 degrees East, the Miers Valley is near the coast of Victoria Land, Antarctica. Although most of Antarctica is covered with ice up to 5 km thick, these mountain valleys have been mostly free of ice and snow for the past 8 million years. Named the McMurdo Dry Valleys, they are ice-free because the Transantarctic Mountains form a dam, holding back the East Antarctic Ice Sheet. These barren valleys provide an enormous opportunity for geological study. For more information on the McMurdo Dry Valleys, read the January 26, 2003, edition of THE ANTARCTIC SUN, available at: www.usap.gov."
