The McMurdo Dry Valleys, Antarctica, receive less than 100 mm (4 in) of precipitation per year and have a mean annual temperature of -20ºC (-4ºF). With an area of around 4,800 km² (1,850 miles²), they represent the largest ice-free area on the continent. Despite the inhospitable conditions, and a complete lack of sunlight for much of the year, this polar desert does support life. [what creatures live here?]
