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

The McMurdo Dry Valleys lie near McMurdo Sound and represent a special Antarctic phenomenon: landscapes that are snow and ice-free due to the extremely limited precipitation and ablation of ice in the valleys. The highest mountain of the TAM is the 4,528 m (14,856 ft) high Mount Kirkpatrick in the Queen Alexandra Range.
