History: Central Asia, 140 Years Ago

Central Asia is an extremely large region of varied geography, including high passes and mountains (Tian Shan), vast deserts (Kara Kum, Kyzyl Kum, Taklamakan), and especially treeless, grassy steppes. The vast steppe areas of Central Asia are considered together with the steppes of Eastern Europe as a homogeneous geographical zone known as the Eurasian Steppe.
Much of the land of Central Asia is too dry or too rugged for farming. The Gobi desert extends from the foot of the Pamirs, 77° E, to the Great Khingan (Da Hinggan) Mountains, 116°–118° E.
Central Asia has the following geographic extremes:
• The world's northernmost desert (sand dunes), at Buurug Deliin Els, Mongolia, 50°18′ N.
