Because they were valleys and they were very dry :D
Taylor Dry Valley is the name of one valley.
Dry valleys are unique in that they contain some of the oldest ice on Earth, dating back millions of years. Despite their name, they are not always completely dry, and can experience occasional meltwater flow during certain times of the year. The extreme cold temperatures and low humidity in these valleys create conditions similar to those found on Mars, making them valuable sites for studying astrobiology.
You can find Antarctica's dry valleys using these coordinates: 77.4667° S, 162.5167°.
The Dry Valleys have been said to mimic the landscape on other planets, including the moon and Mars.
The McMurdo Dry Valleys in Antarctica are extremely dry and lack snow or ice. They have been compared to the surface of the planet Mars, because the environment is so extreme. Read more, below.
Technically endolithic photosynthetic bacteria live in the dry valleys as do anaerobic bacteria.Since these life forms are not readily visible, it is often said that there are no living things there.These dry valleys are often compared to Mars.Read more, below.
Yes, Antarctica has several valleys, including the notable Dry Valleys, located in the McMurdo Dry Valleys region. These valleys are characterized by their unique topography and are among the driest places on Earth, receiving very little precipitation. They are significant for scientific research, as they provide insights into climate and ecosystems. Other valleys in Antarctica, such as those formed by glacial activity, contribute to the continent's diverse geological features.

The McMurdo Dry Valleys lie across McMurdo Sound from the McMurdo Research Station, and are areas devoid of ice. This landscape has been compared to the surface of the planet Mars.
Because southern California, which is mostly valleys and deserts, is very dry and barely gets any rain and the heavy winds make it great for fires to get out of control
Antarctica's Dry Valleys -- a region of Antarctica near the New Zealand scientific research station and one American station -- are barren. There may be a temporary scientific hut occupied for a few weeks during the austral summer, especially near Lake Vanda. Otherwise, the Dry Valleys have been compared to the surface of the planet Mars.
An umbrella gets wetter but it keeps you dry.
