Gobi Desert, Mongolia

The Gobi desert, one of the world's great deserts, covers much of the southern part of Mongolia. Unlike the Sahara there are few sand dunes in the Gobi; rather you'll find large barren expenses of gravel plains and rocky outcrops. The climate here is extreme. Temperatures reach +40° C. in summer, and -40 in winter. Precipitation averages less than 100 mm per year, while some areas only get rain once every two or three years. Strong winds up to 140 km/h make travel dangerous in spring and fall. Great Gobi National Park is one of the largest World Biospheres, with an area larger than Switzerland. It contains the last remaining wild Bacterian (two-humped) camels, wild ass, and a small population of Gobi bears, the only desert-inhabiting bear.
