Nepal being the mountainous country has a great many Himalayan ranges. These Himalayan ranges form a great mountain system of Asia standing as a barrier between Tibetan Plateau to the north and alluvial plains of the Indian subcontinent to the south. The Himalayas of Nepal include more than one hundred and ten snowcapped peaks rising to elevations of 7,300 meteres or more above sea level. The highest mountain Mt. Everest, also known as Chomolungma in Tibetan, Qomolangma Feng in Chinese and Sagarmatha in Nepali is the world’s highest mountain with an elevation of 8848 m. The high summits of these mountains rise into the zone of unceasing snow.
The Himalayan ranges occupy most part of Nepal being extended into Sikkim in India and Tibet, the autonomous region of China. The Highest part of the Himalayan ranges, also called the great Himalayas, roughly follows the the Nepal-Tibet border holding many of the World’s highest peaks such as Mt. Everest (8,848m), Mt. Kanchenjunga (8,586 m), Mt. Makalu (8,463 m), Mt. Dhaulagiri (8,167 m), Mt. Manaslu (8,163 m), and Mt. Annapurna (8,091 m). These perennial snowcapped mountains form huge glaciers, that creates a number of rivers. These rivers apart from their tributaries in their waydown flow southward through deep ravines and watershed between the Brahmaputra and the Ganges. The Great Himalayas stands as a climatic barrier between Indian lowland plains and the Tibetan high plateau. The uncultivated, uninhabitable highlands and the steep rocky banks of the trubulent rivers cause major difficulty to human travel. Nevertheless, there are a few passes at an elevation betweeen 5000m and 7000 m and river valleys allow human habitation, grazing and agriculture at an elevation of 5000m.
