McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999. The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross ...
McMurdo has the southernmost harbor in the world, but for access by ships icebreakers can be needed to establish passage. Three Enercon E-33 (330 kW each) wind turbines were deployed in 2009 to power McMurdo and New Zealand's Scott Base, reducing diesel consumption by 11% or 463,000 liters per year.

The way station at Marble Point is located on a narrow strip of land between Wilson Piedmont Glacier and the sea, about 50 mi (80 km) from McMurdo Station.United States military forces built the camp on the western shores of McMurdo Sound in 1956 in conjunction with the forthcoming 1957–58 International Geophysical Year (IGY).

The annual snowfall on Ross Island averages only 17.6 centimetres (6.9 in). Snowfall in Antarctica's interior is far less at 5 centimetres (2.0 in). Snow seldom accumulates on the McMurdo Dry Valleys on the western shores of McMurdo Sound. McMurdo Sound provides an important component in Antarctica's global effects upon climate.
The Wright Valley is the central one of the three large McMurdo Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound. Wright Valley contains the Onyx River, the longest river in Antarctica, Lake Brownworth, the origin of the Onyx River, and Lake Vanda, which is fed by the Onyx River.
