The Dry Valleys of Antarctica get virtually no snowfall or moisture of any kind. Researchers come not only to study one of the world's most delicate, yet simple ecosystems, but also to learn more about the unique geological formations and processes occurring there. From south to north, the principal ice-free valleys include the Taylor, Wright, McKelvey, Balham, Victoria, and Barwick Valleys. Similar but smaller valleys also occur farther south, along the coast of McMurdo Sound and the western margin of Koettlitz Glacier; these include, from south to north, Miers, Marshall, and Garwood Valleys, and the Salmon Stream valley.
