Himalayas (hĬmäl´əyəz, hĬməlā´əz)
Himalayas (hĬmäl´əyəz, hĬməlā´əz) [Sanskrit,=abode of snow], great Asian mountain system, extending c.1,500 mi (2,410 km) E from the Indus River in Pakistan through India, the Tibet region of China, Nepal, E India, and Bhutan to the southern bend of the Brahmaputra River in SE Tibet. For most of its length, the Himalayas comprise two nearly parallel ranges separated by a wide valley in which the Indus and Sutlej rivers flow westward and the Brahmaputra flows eastward. The northern range is called the Trans-Himalayas. The southern range has three parallel zones: the Great Himalayas, the perpetually snow-covered main range in which the highest peaks (average elevation 20,000 ft/6,100 m) are found; the Lesser Himalayas with 7,000 to 15,000 ft (2,130–4,570 m) elevations; and the southernmost Outer Himalayas, 2,000 to 5,000 ft (610–1,520 m) high. A relatively young and still growing system subject to severe earthquakes, the Himalayas' main axis was formed c.25 to 70 million years...
