The three largest mountain ranges on the Antarctic continent are the Transantarctic Mountains, the West Antarctica Ranges, and the East Antarctica Ranges. The Transantarctic Mountains compose a mountain range in Antarctica which extends, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges.
The summits and dry valleys of the TAM are some of the few places in Antarctica not covered by ice, the highest of which rise more than 4,500 metres above sea level. The 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 4,528 m high Mount Kirkpatrick in the Queen Alexandra Range.
